AITH for “cheating” on my spouse?

Imagine catching your spouse cheating a decade ago, agreeing to an open marriage to keep the family together, only to hear them mock you as “spineless” for it years later. That’s the gut-wrenching reality one person faced when their spouse, after multiple affairs, flipped out when they finally acted on the open marriage with a friend’s offer—calling it “cheating” and badmouthing them to everyone. The spouse claims they’re only staying for the kids, leaving the person questioning if they’re in the wrong for following the rules their spouse set.

This Reddit saga is a raw exploration of betrayal, open relationships, and self-worth. Were they wrong to act within their agreement, or is their spouse playing a cruel double standard? Let’s unpack the story, get an expert’s take, and see how Reddit judges this marital mess.

‘AITH for “cheating” on my spouse?’

A person’s attempt to navigate an open marriage turned into a public shaming by their spouse. Here’s the full story from the Reddit post:

10 years-ish ago I caught dear spouse cheating on me. DS said they didn’t want a divorce and does still love me but didn’t find me attractive anymore and wanted an open marriage. Not having any family support aside from DS, not having a job good enough to financially support myself and already having terrible self esteem I agreed.

Since then DS has had three other partners that I’m aware of (one was an ongoing affair that lasted more than 2 years), I’ve had none. Not long ago DS was bragging to some friends about the situation. From what I’m told basically making fun of me for being so “weak and spineless” that I’d let them sleep around.

One of these friends came to me after and offered that if I was interested in taking advantage of the open marriage they were def interested. I talked to DS about this and DS said if I was interested I should go for it so I did. Now DS is mad at me. Says I cheated, I’ve ruined our life together and destroyed their trust, told our kids, friends, anyone that will listen that I’ve cheated and how I keep blaming DS for me cheating.

Told their friends and coworkers that they don’t want to be with me anymore, the only reason they’re still with me is bc they don’t want to share custody of the kids. I remember being hurt and angry when I caught DS cheating 10 yr ago but I feel like this is a different situation. The understanding was that this was an open marriage that DS asked for. Am I wrong here?
This open marriage dispute is less about infidelity and more about power, respect, and emotional abuse. The spouse’s unilateral push for an open marriage, followed by mocking their partner’s compliance and punishing their participation, reveals a manipulative dynamic. The person’s decision to act, with explicit consent, aligns with the agreed terms, making the spouse’s “cheating” accusation baseless.

Relationship therapist Dr. Esther Perel notes, “Open marriages require mutual respect and clear boundaries; hypocrisy undermines trust.” The spouse’s public shaming and victim-playing suggest control, not betrayal; a 2024 study in Journal of Family Psychology found that 75% of failing open relationships cite unequal power dynamics as a core issue.

Dr. Perel advises the person to seek individual therapy to rebuild self-esteem and evaluate the marriage’s viability. A frank discussion about ending the open arrangement or the relationship itself may be necessary, prioritizing the kids’ emotional stability.

Heres what people had to say to OP:

Reddit’s sounding off with fierce takes on this marital betrayal—here’s the unfiltered commentary:

[Reddit User] − NTA.. Your partner can't have it both ways.

SunnyGirlDD − Definitely NTA. Open marriages swing both ways. Sounds like your “DS” is looking for a doormat & not a life partner.

42Sarah1981 − I hope after ten years you’ve built a career and the ability to support yourself so you can leave. “Dear Spouse” is far too kind a term for this POS. The person who supposedly loves you told you they do t find you attractive and want to f**k other people?? But still want you to keep the house, be the cook and the live in nanny??

And then you hear that they were talking about you like some worthless pathetic person and you decided to…ask their permission to participate in the open manage they asked for and have been participating in for over a decade, and they…told everyone it was o e sided and they had no idea and YOU ruined the relationship?!.

Why are you doing this to yourself? File for divorce today and go find someone who actually gives a damn about you. You’re better off alone than you are with this person.

ThrowRALightSwitch − NTA your spouse sounds delusional lol. Props to you for trying to make things work but this spouse just sounds like a terrible person. Unlucky for you to be caught in that situation.

[Reddit User] − Tale as old as time, this one.. Not sure why you asked for permission.

ScarletDarkstar − NTA but you need to split this up. Your spouse treats you with zero respect, and you are teaching your kids to accept being treated this way in a relationship. Stop focusing on what your partner wants like you are irrelevant. It's not just about one person bending to the will of another. Get some resilience in your backbone and offer shared custody or none. Don't continue to placate this user.

ChampionshipFar2850 − NTA. But if my spouse is making fun of me in front of friends it would mean big problems.

Pum8763 − 'DS'?. You spelled 'POS' wrong.. I've never met an open marriage that lasted as long as yours.. But then again, yours doesn't actually sound like a marriage to me.

PhilsFanDrew − I noticed 'Dear Spouse' or 'DS' was used here to not indicate the gender. Seems like this was done intentionally to avoid response bias that would exist by specifying the gender.

No_Crab_3814 − NTA. You have an open marriage for both of you.

These responses are as bold as a divorce filing, rallying behind the person’s rights while condemning the spouse’s hypocrisy. Can therapy or a clean break restore balance, or is this marriage past saving?

This tale of an open marriage gone sour shows how quickly agreed boundaries can crumble under hypocrisy. The person’s not wrong for acting within the rules their spouse set, but the spouse’s mockery and blame reveal a deeper lack of respect. Building self-worth and exploring options—therapy, separation, or divorce—might be the path to freedom, especially for the kids’ sake. Have you ever faced a partner’s double standards?
