He Blames Me for the Affair
He's telling you, in one form or another, that this happened because you weren't attentive enough, or because you gained weight, or because you were always tired, or because the marriage was already broken and he just found comfort elsewhere. Here's how to sort what's actually true from what's a defense.

The short answer
A struggling marriage can be a real, shared problem worth examining, but it never makes cheating an inevitable or justified response. He had other options at every point, and choosing this one was his choice alone, regardless of what else was going wrong.
What matters most here
- Marital problems are usually shared and worth honest examination, but infidelity is always a unilateral choice, not an automatic consequence.
- Blame-shifting after an affair is a well-documented pattern precisely because it protects the person who cheated from full accountability.
- You can acknowledge real issues in the marriage without accepting responsibility for his specific choice to cheat.
- Watch for the difference between him taking ownership with context versus using context to escape ownership entirely.
- Believing his blame narrative too fully can quietly erode your own sense of reality over time.
Why blame-shifting is such a common response
When someone is confronted with having done something they know is wrong, a very common defense is to reframe the story so the responsibility feels shared or even primarily someone else's. This isn't unique to affairs, it shows up whenever people are caught doing something they can't fully justify to themselves.
For him, blaming the marriage, or specifically you, protects him from having to sit with the full weight of having chosen this. It's psychologically easier to say 'you drove me to it' than 'I made a selfish choice that hurt you badly,' even if the second statement is closer to the truth.
Recognizing this pattern doesn't mean every complaint he raises about the marriage is automatically false. It means the timing and function of the complaint, showing up specifically as a defense for cheating, deserves scrutiny.
The real distinction between a shared problem and a unilateral choice
Marriages genuinely can have real problems that both people contributed to: disconnection, unmet needs, poor communication, resentment built up over years. It's entirely possible those things were true in your marriage and worth honestly examining, regardless of the affair.
But there's a hard line between 'our marriage had real problems' and 'therefore cheating was a reasonable response to those problems.' Countless people in genuinely difficult marriages don't cheat. They leave, they go to counseling, they have a hard conversation, they struggle silently, they do any number of other things. Cheating was always one option among many, and he picked it.
You can hold both truths at once: the marriage may have had real issues worth acknowledging, and he is still fully responsible for choosing infidelity as his response to them. One does not cancel or excuse the other.
Watching for the difference between context and excuse
There's a version of him explaining what was going on for him that still includes real ownership: 'I felt disconnected and instead of talking to you about it honestly, I made a terrible choice, and that's on me.' This kind of statement offers context without using it to escape responsibility.
Compare that to: 'if you hadn't been so distant, this wouldn't have happened,' which places the actual cause of his choice onto you. Listen closely for which version he's actually offering, since they can sound superficially similar in a tense conversation.
A useful test is whether his explanation ends with him owning the choice or with you feeling like you now need to apologize for something. If accountability conversations keep ending with you somehow comforting him or defending yourself, that's the excuse version, not the context version.
How this blame can quietly distort your own thinking
If you hear a version of 'this is partly your fault' enough times, especially from someone you love and trust, it can start to seep into how you see yourself, even when you know intellectually it's not accurate. This is a real risk worth naming to yourself directly.
It can help to write down, plainly, what actually happened and whose choice it was, in moments when you're thinking clearly, so you have something concrete to return to when his version starts to feel more convincing than your own memory of events.
Talking this through with a therapist or a trusted friend outside the situation can also help you keep your grip on reality, since an outside perspective isn't subject to the same pressure his narrative puts on you directly.
Responding to blame in real time
You don't need to win a debate every time he brings up the marriage's problems as an explanation. A calm, firm line like 'I'm willing to talk about what wasn't working between us, but that's a separate conversation from you choosing to cheat' keeps the two issues from collapsing into one.
If he consistently can't have a conversation about the affair without redirecting to your shortcomings, that pattern itself is important information about whether he's actually capable of the accountability real rebuilding requires.
It's fine to say plainly that you're open to hearing feedback about the marriage generally, at a different time, but that this particular conversation is about his choice and his accountability for it.
When this pattern signals something bigger
If blame-shifting is a persistent, unchanging response no matter how many times you've named it, it can point to a broader pattern of avoiding responsibility that extends beyond just this one event, worth watching for elsewhere in the relationship too.
This doesn't automatically mean the marriage can't be saved, but it does mean any rebuilding process needs real accountability as a precondition, not a hoped-for eventual outcome he'll get to later.
If a genuine acceptance of responsibility never actually arrives, despite time and conversation, that absence is itself a clear, if painful, answer about what continuing to try would actually involve.
What to do, in order
Step 1
Separate the two conversations explicitly
When he raises marital issues as an explanation, name directly that you're willing to discuss those separately, but that this conversation is specifically about his choice and his accountability.
Step 2
Write down your own account of events
Keep a private, honest record of what actually happened and whose choice it was, to anchor yourself against a narrative that shifts blame onto you over repeated conversations.
Step 3
Notice whether his explanations end in ownership or deflection
Pay attention to whether his statements conclude with him taking responsibility or with you somehow needing to reassure or apologize to him. That pattern tells you a lot.
Step 4
Bring in a neutral third party if conversations keep circling
A therapist experienced with infidelity can help structure these conversations so that legitimate marital feedback and accountability for the affair don't get tangled together unproductively.
Step 5
Check your own thinking against an outside perspective
Talk through what he's telling you with a trusted friend or therapist periodically, to make sure his framing hasn't quietly become your own belief about what happened.
What makes this harder than it needs to be
Accepting full responsibility to end an uncomfortable conversation
Agreeing that the affair was significantly your fault just to defuse tension in the moment reinforces a false narrative that becomes harder to correct the longer it goes unchallenged.
Refusing to examine any real marital issues at all
Dismissing every legitimate concern he raises about the marriage, purely because he raised it in a blame-shifting context, can prevent honest examination of things worth addressing regardless of the affair.
Debating the blame narrative every single time it comes up
Getting pulled into a fresh argument each time he shifts blame can be exhausting and unproductive. A firm, brief redirect is often more effective than a full re-litigation each time.
Isolating from outside perspective while absorbing his narrative
Processing this entirely alone with him as your only source of interpretation makes it easier for a distorted version of events to take hold. Keep outside voices in the mix.
Questions women ask
Is it possible the marriage really was partly to blame?
Marriages can genuinely have real, shared problems worth examining honestly, but that's a separate question from whether cheating was a justified response to those problems. It generally wasn't, since other options were always available to him.
How do I respond when he says I drove him to it?
You can acknowledge you're willing to discuss real issues in the marriage separately, while stating clearly that his choice to cheat was his own decision, not an inevitable consequence of anything you did.
Why does he keep bringing up my flaws instead of apologizing?
This is a common defensive pattern that shifts focus away from his own accountability. It doesn't necessarily reflect the truth about the marriage as much as it reflects discomfort with fully owning what he did.
Should I apologize for anything I did wrong in the marriage?
If there are genuine things you'd like to acknowledge about your own contributions to marital problems, you can do that on your own terms, separately from and not as compensation for his choice to cheat.
What if I start believing it really was mostly my fault?
That's a sign worth taking seriously, since repeated blame-shifting can distort your sense of reality over time. Talking to a therapist or trusted outside person can help you regain a clearer, more accurate picture.
Whatever was or wasn't working in your marriage, the choice to cheat was made by him, alone, in a moment he could have chosen differently. No accounting of your flaws changes that basic fact.
You're allowed to hold space for honest reflection about the relationship without accepting a share of blame for his specific decision. Those are genuinely two different conversations, even when he tries hard to merge them into one.
Trust your own memory of what actually happened, even when his version keeps insisting on something else. You were there too, and your account matters just as much as his.
