Forgiveness is one of the more complicated things you can do for someone you love. It is not the same as excusing a behavior, and it is not the same as pretending something didn’t happen. Real forgiveness is a deliberate internal decision – but it is also something you give freely, not something a partner is automatically owed just because time has passed or because they apologized. Some things in a relationship don’t call for forgiveness. They call for a clear-eyed look at whether this relationship is still something you should be in.
The cultural script around romantic relationships tends to romanticize endurance. Staying through difficulty is often confused with loyalty. Forgiving everything gets reframed as love. But there are behaviors that corrode the foundation of a relationship so completely that no amount of couples therapy can fully rebuild what was there. The list of things to never forgive a partner for isn’t about being uncharitable or holding grudges for sport. It’s about knowing where your non-negotiables are before someone crosses them.
What follows are 20 of those lines. Some are obvious, a few are less so, and several are the kind of thing people routinely minimize because the harm doesn’t leave visible marks.
1. Any Form of Physical Violence
Physical violence against a partner is not a relationship problem. It is a safety problem, and conflating the two is one of the most dangerous things a person can do. According to the CDC, more than 1 in 3 women and more than 1 in 6 men have experienced contact violence, physical violence, or stalking by an intimate partner during their lifetimes. One incident does not mean isolated. One apology does not mean it won’t happen again.
The pattern of physical abuse almost never begins at its worst. It escalates. A shove leads to a slap leads to something more serious, and by the time a person recognizes how dangerous the situation has become, they have often already excused a long chain of prior incidents. Physical violence is not something to repair around. It is the thing you leave.
2. Assault or Coercion
A partner who pressures, manipulates, or forces acts on you has committed an assault. This remains true regardless of marital status, regardless of prior consent to other acts, and regardless of how the partner frames it afterward. Coercion does not require physical force. A partner can pressure someone into intimacy through guilt, emotional manipulation, or simply refusing to accept “no” – wearing the other person down until they give in just to end the conflict. None of that is consent.
Partners who engage in coercion rarely experience it as assault on their end. They often describe it as persistence, or as something the other person “went along with.” That framing is part of what makes it so damaging – because the person who was coerced often ends up doubting their own experience. This is a line that does not move.
3. Repeated Dishonesty and Compulsive Lying
Trust is not a value-add in a relationship. It is the architecture. Without it, every interaction becomes a calculation. The Knot’s 2024 Relationship & Intimacy Study, which surveyed over 1,000 singles and 1,000 married couples, found that lack of trust and honesty is the most common relationship deal breaker, cited by 63% of respondents.
A partner who lies habitually – about money, about where they’ve been, about who they’ve been talking to, about things that don’t even seem to require lying – is not a partner who made a mistake. Lying as a pattern is a coping mechanism, a way of managing how they are perceived without ever becoming a different person. One lie, discovered, explained, and genuinely addressed, is not the same thing. A recurring pattern of dishonesty, especially when confronted and denied, is a different animal entirely.
4. Infidelity That Was Prolonged or Deliberately Hidden
Infidelity is complicated territory, and a single incident handled with full honesty and genuine accountability is something some couples do manage to move through. But a prolonged affair – one that continued for months or years, involved deliberate, sustained deception, potentially included emotional intimacy with another person, and may have put your health at risk – is categorically different. The betrayal isn’t just the act. It’s every day that followed, every lie told to cover it, every moment you were denied the chance to make an informed decision about your own life.
Research published in Personal Relationships, which studied forgiveness and unforgivable acts in romantic relationships, identified infidelity as one of the most commonly cited unforgivable transgressions among both dating and married individuals. The people in that research weren’t being rigid. They were recognizing that certain betrayals change the relationship permanently – not because forgiveness is impossible, but because what existed before can’t be exactly reconstructed.

5. Financial Abuse or Deliberate Economic Control
Financial abuse is one of the most underrecognized forms of partner abuse, in part because money has so many legitimate reasons to be complicated in a relationship. But there is a clear line between a couple navigating financial difficulty together and a partner who controls money as a method of power. This looks like: withholding access to bank accounts, sabotaging your employment, running up debt in your name without your knowledge, giving you an “allowance” while they control all other funds, or threatening financial ruin as a way of keeping you from leaving.
Research consistently finds that economic abuse appears in the vast majority of domestic violence cases – estimates across studies range from 94% to 99% – which means it rarely travels alone. A partner who controls money as a weapon is also, almost always, exercising control in other areas of the relationship. The financial piece is often the last thing addressed because it’s the thing that makes leaving hardest. According to CDC national data, the lifetime economic cost of intimate partner violence reaches approximately $3.6 trillion at the national level – a number that reflects lost wages, medical costs, and legal expenses, but says nothing about the years spent rebuilding a life from scratch.
6. Emotional Abuse and Sustained Psychological Manipulation
Emotional abuse is harder to document than physical abuse, which is part of why it persists so effectively. It includes name-calling, constant criticism, open contempt, threats, humiliation in front of others, deliberate efforts to wear down a person’s self-worth, and using fear as a management tool. Running beneath all of it is control — the systematic reduction of a partner’s autonomy until leaving feels impossible. Michele Goldman, PsyD, a licensed clinical psychologist, describes these behaviors as “significant issues that result in feeling unsafe or disrespected” – to the point that the foundation of a relationship is brought into question.
The damage from sustained emotional abuse accumulates in ways that make it difficult to recognize from inside it. People in emotionally abusive relationships often describe a slow erosion – of confidence, of their sense of what is normal, of their trust in their own perceptions. By the time they recognize what’s happening, they’ve often spent years rebuilding themselves around accommodating the abuser.
7. Gaslighting That Is Deliberate and Sustained
Gaslighting is a specific form of manipulation in which a partner systematically causes you to doubt your own sense of reality. Not a one-time argument where your partner insists their version of events is correct. Not disagreeing over what was said in a particular fight. Sustained gaslighting is a pattern in which you are made to feel repeatedly confused, irrational, or unstable for responding to things that actually happened.
The difference between an argument about memory and deliberate gaslighting comes down to consistency and intent. A partner who gaslights you does not occasionally misremember. They consistently deny, reframe, and redirect in ways that always serve them and always leave you doubting yourself. If you find yourself saving texts just to confirm to yourself that a conversation happened, that’s not paranoia. That’s you managing a system that has been designed to undermine you.
8. Using Your Children as Leverage
A partner who threatens to take your children away, uses parenting time as punishment, manipulates children against you, or withholds access to your kids as a method of controlling your behavior, has weaponized the most significant relationships in your life. This behavior does not exist in a vacuum. It is almost always part of a broader pattern of controlling behavior, and it causes harm to children that extends well beyond the immediate conflict between the adults.
Children who witness one parent being used as a weapon against the other internalize those dynamics. They learn that love comes with leverage. They learn that the people who are supposed to protect them will use them as instruments when it’s convenient. The damage to children from being used this way is real, documented, and long-lasting.
9. Threatening You, Your Children, or Your Pets
A threat is not an argument. A partner who says “I’ll make sure you never see the kids again,” or “I know where you go,” or who makes any statement designed to produce fear rather than resolution has crossed into a category that requires immediate attention. Threats that target children or pets are calculated to hit the places where you are most vulnerable, and they often escalate.
Threats in relationships rarely arrive fully formed. They start as implications – a certain tone, a reference to what they could do if they wanted to. By the time a threat is spoken directly, it has usually been preceded by a long pattern of smaller intimidations that have already taught you to be afraid. A partner who has learned to keep you in line through fear is not a partner in any meaningful sense.
10. Stalking or Surveillance
A partner who tracks your location without your knowledge or consent, reads your messages, installs monitoring software on your devices, arrives at places you never told them you’d be, or monitors your social media specifically to gather evidence against you is not being protective. They are surveilling you. There is no relationship-appropriate version of that behavior.
This one sometimes gets minimized in the early stages of a relationship when it’s framed as jealousy or concern. It is neither. Jealousy does not require a tracking app. Concern does not require reading someone’s private messages. Surveillance is about control, and a partner who surveils you at the beginning of a relationship will not simply stop when you ask them to.
11. Publicly Humiliating You
There is a meaningful difference between a partner who embarrasses you by accident – the story they told at a dinner party that you wish they hadn’t, the offhand joke that didn’t land – and a partner who uses public settings as an arena for humiliation. A partner who mocks you in front of your friends, belittles you at family gatherings, criticizes you in front of your children, or deliberately undermines you in social situations is doing something deliberate. The audience is the point.
Public humiliation in relationships functions as a form of verbal abuse that is especially damaging because it creates witnesses to your diminishment. It recruits other people into the dynamic, makes you feel that the humiliation is deserved (otherwise why wouldn’t they protect you from it?), and is often explained away later as a joke you failed to find funny. That pattern has a name, and the name is not “sense of humor difference.”
12. Exposing or Threatening to Expose Private Images
Sharing or threatening to share intimate images without consent – sometimes called non-consensual pornography or image-based abuse – is illegal in most U.S. states and causes profound, lasting harm. The threat alone, even if never carried out, is a method of coercion designed to trap the person in the relationship or punish them for trying to leave.
This form of abuse has increased significantly in the digital age and disproportionately affects women. A partner who has used this threat even once has told you exactly what they are capable of. There is no context in which that threat is part of a healthy relationship, and no version of an apology that makes it safe to stay.
13. Isolating You From Family and Friends
Isolation doesn’t usually announce itself. It starts with opinions – small comments about how a particular friend is a bad influence, or that your mother doesn’t respect the relationship, or that you always seem different after spending time with your sister. Those comments become requests. The requests become arguments. The arguments become conditions. Eventually you look up and realize your social world has contracted to the size of one person.
A partner who deliberately works to cut you off from your support network is not protecting the relationship. They are removing your ability to get perspective on it, to have people who know you well enough to notice changes in you, and to have somewhere to go if you need to leave. Isolation is one of the most consistent precursors to deeper abuse.
14. Addiction That Is Denied, Hidden, or Consistently Prioritized Over You
Loving someone who struggles with addiction is one of the more painful positions a person can be in, and it deserves real compassion. But there is a genuine difference between supporting a partner through active and honest engagement with their addiction, and being in a relationship with someone who hides their use, lies about it, and allows it to cause harm to you and any children in the household while denying that anything is wrong.
A partner who is in active, honest recovery – who is doing the actual work, who is accountable, who is not asking you to cover for them – is in a different category. A partner who is actively using, lying about it, depleting shared finances, potentially putting children at risk, and refusing to acknowledge the problem is asking you to participate in your own harm. Those are two different situations, and they require two different responses.
15. Repeated Manipulation Tactics After Explicit Conversation
Everyone deploys some level of interpersonal strategy in relationships. That’s not manipulation. Manipulation is specific: it is the deliberate use of guilt, shame, fear, confusion, or false information to get a partner to do something they have already said they don’t want to do, or to avoid accountability for something they’ve done. A partner who apologizes genuinely and adjusts their behavior has made a mistake. A partner who apologizes and then does the same thing – using the same tactic, in the same way, producing the same result – is telling you who they are.
The most common versions of this include the guilt trip that always materializes when you try to raise a concern, the dramatic crisis that appears right when you’ve decided something has to change, and the love-bombing that follows a significant hurt. These are not coincidences. They are patterns, and patterns are the thing you have to believe over words.
16. Contempt
Contempt in a relationship is different from anger, frustration, or even ongoing conflict. Contempt is the expression of disgust and disrespect – the rolled eyes, the dismissive sneer, the mocking tone, the treating of a partner as fundamentally beneath them. It is the single behavior that relationship researchers have most consistently identified as predictive of relationship failure.
A partner who holds you in contempt has stopped seeing you as a person they respect. Anger implies engagement. Contempt implies that you’ve been written off as not worth taking seriously. A relationship can survive disagreement, incompatibility on various dimensions, even the aftermath of real betrayals. It is very difficult to survive one partner’s sustained contempt for the other.
17. Refusing Accountability Across Multiple Incidents
A partner who cannot take responsibility for their impact on you – who sidesteps, minimizes, reframes, blames you, or simply refuses to acknowledge that something they did caused harm – is not someone you can have a real relationship with. Accountability is how trust gets repaired. Without it, every injury just gets added to the pile.
The pattern to watch for is not a single refusal to apologize. It’s a consistent pattern across different issues, different arguments, different years. If every disagreement ends with you somehow being the one at fault, if apologies only come when there’s something to be gained from them, if the same issues circle back because nothing ever actually changes – that’s not incompatibility. That’s a person telling you they will not be held accountable by you, ever.
18. Cheating Specifically Designed to Hurt You
There are different kinds of infidelity, and context matters even when it doesn’t excuse. But some infidelity is not impulsive, not situational, and not about unmet needs in the relationship. Some of it is targeted – the affair with your close friend, the hookup at the party you both attended and then lied about that same night, the contact with your sibling. These are not lapses. They are choices designed to cause a specific kind of harm.
When infidelity is structured in a way that maximizes the damage to you specifically, the act is inseparable from its intent. The person who sleeps with your best friend of fifteen years and then tells you it “just happened” is asking you to ignore the most obvious thing in front of you. Some things to never forgive a partner for are painful because they were thoughtless. This one is worse because it wasn’t.
19. Weaponizing Your Mental Health Against You
A partner who brings up your depression in arguments as evidence that you’re unreliable, who uses your anxiety to dismiss your concerns, who frames your past therapy as proof that you’re unstable, or who weaponizes a disclosure you made in a vulnerable moment to undermine you in a future conflict – that is a specific and calculated form of cruelty. You trusted them with something real. They filed it away for later use.
This dynamic makes it harder for people to seek help, because the act of acknowledging a mental health struggle becomes a liability. It also creates a kind of learned silence: you stop disclosing, stop asking for support, stop being honest about how you’re doing, because you’ve learned that honesty will be turned around. That is not a relationship. That is a penalty for being human.
20. Making You Feel Consistently Worthless
This one is harder to name than the others because it doesn’t reduce to a single incident. It is the cumulative effect of years of being told, in explicit and indirect ways, that you are not enough. Not smart enough, not attractive enough, not capable enough, not deserving of the love you want, not worth protecting, not worth choosing. A partner who consistently makes you feel small – through criticism, through comparison to others, through indifference to your accomplishments, through making their love feel conditional on you performing correctly – is causing harm just as real as any on this list.
The CDC’s most recent national data estimated the lifetime cost of intimate partner violence at approximately $103,767 per female victim, totaling nearly $3.6 trillion nationally – figures that capture economic damage but say nothing about the years a person spends rebuilding a sense of self after a relationship that ground it down. The toll of feeling worthless in your own home, beside the person who is supposed to know you best, never registers in any dataset. But it is real, and it compounds.
What This Is Really About
This is not a list built on the premise that people don’t make mistakes, or that imperfect behavior is automatically unforgivable, or that relationships don’t require tolerance and compromise and the willingness to work through hard things. Most of what makes a relationship durable is unglamorous and repetitive: the choosing of each other across small moments, the returning to difficult conversations, the ongoing negotiation of two lives in proximity.
But there is a difference between the hard and the harmful. The things on this list are not rough patches, not incompatibilities to grow through, not misunderstandings that better communication would resolve. They are patterns of behavior that treat you as something to be managed, deceived, controlled, or diminished. Some of these patterns started long before you came along – they are how that person learned to move through the world – and naming them is not the same as fixing them.
You do not have to wait until something has happened a hundred times before you’re allowed to call it what it is. The list of things to never forgive a partner for isn’t really about forgiveness at all. It’s about what you will build your life around, and whether that thing still deserves to be your foundation.
