AITA for telling my dad’s partner she knew he was still married when she started dating him and I’m not here to make that easier on her?

Family dynamics can be extremely intricate, especially when legal and emotional ties tangle together over decades. In this story, a young man is caught in the middle of a sensitive issue involving his dad’s partner, who frequently laments the complications of being with a man who is still legally married.

Tired of being subjected to the constant venting and emotional burden, he finally reached his breaking point at a family gathering. His response was direct and unapologetic—he made it clear he wasn’t there to smooth over issues that she should have already accepted.

‘AITA for telling my dad’s partner she knew he was still married when she started dating him and I’m not here to make that easier on her?’

My parents have been

The reason? They don't want to split their assets in a divorce. Argued over it and almost divorced twice but always ended the proceedings because neither wanted to lose in the divorce.

So they remained legally married and operate day to day like divorced people. Both have been in other relationships and when me and my siblings (26m and 27f) were kids they split custody of us. It was always kind of crazy because we'd say we had divorced parents when we didn't really and on the outside it looks that way.

But when you're close to us you find out for one reason or another. My mom and dad are both with long term partners now. Both of the partners have issues with the fact they're still technically with married people and can't get married to them. My mom's guy learned fast that me and my siblings didn't want to hear bitching about that.

My dad's partner is different. She keeps trying to talk to us about it and speaking for myself, I have tried to be diplomatic and kind but asking her not to drag me into relationship issues. But she refuses to let it go. She wants to cry about it to us and have us say we hate it for her and offer advice or tell her what to do.

It's damn weird since these are our parents she's bitching about. Last weekend she cornered me at my grandpa's birthday and started unloading her frustration on me about it. In a maybe too-harsh way I told her to stop. I said she knew dad was still married when she stated dating him and she had to accept that fact because I'm not here to make that easier on her.

I said she was driving me crazy and to shut up already. She told me I didn't need to be so uncivil and volatile toward her. And she had a real attitude the rest of the party. Dad asked me about it and I told him everything that happened and he acted like I never said anything. Then she texted and demanded an apology.. AITA?

Family therapists and conflict resolution experts agree that setting clear personal boundaries is essential—especially in blended families with complicated histories. In this case, the author’s outburst, while abrupt, was a reaction to being repeatedly drawn into an ongoing emotional drama that wasn’t his responsibility.

Psychologists point out that individuals who frequently vent their personal issues often expect those around them to serve as emotional crutches. However, healthy relationships require each person to manage their own feelings rather than offloading them on others consistently. It’s critical to communicate that while empathy is valuable, it doesn’t obligate someone to be the designated problem solver for another’s ongoing issues.

Legal and social experts also note that understanding the context of longstanding family dynamics can help clarify responsibilities. Given that the dad’s partner was fully aware—before the relationship even began—of the legal entanglements, her choice to persist in complaining ultimately becomes her own responsibility.

The author’s stance reflects an important real-world lesson: one is under no obligation to make someone else’s difficult situation any easier, especially when that person is aware of all the underlying facts.

Here’s what Redditors had to say:

Many Redditors wholeheartedly supported the author’s decision. Commenters emphasized that expecting him to constantly absorb and validate the partner’s frustrations was unreasonable. They argued that she had every opportunity to address her issues directly with his dad or through personal counseling and that her behavior was a red flag regarding emotional manipulation.

Multiple voices in the community stated that, regardless of how uncomfortable the situation might have been, the author was not obligated to act as an emotional buffer for a situation he did not create.

[Reddit User] − NTA Her expecting sympathy from the kids is f**king insane and her not being respectful to keep you out of it is a huge red flag for dad that he’s oblivious to or ignoring

Shot_Potential3871 − NTA. People need to stop thinking that they will change others, then get mad when it doesn't change. She is even more of an AH and manipulative to try to drag kids into it. Tell her to talk to your dad, you don't owe her an apology. But she should apologize to you for involving you in matters that don't include you.

Bubbly_Source_2965 − NTA, you’re not her therapist and unloading on you has absolutely no effect on your parent’s marital standing. It’s just annoying. What does she expect? Does she think she can convince you think the same way and use you as leverage to convince your dad to go through with the divorce??

It’s absolutely pointless to complain to you about the situation when you’re the one that has lived through the situation literally your entire life. Maybe she wants to just vent, but you’re not one of her girlfriends. IMO I think she’s trying to get the kids onboard to push the idea of divorce, otherwise why get you involved at all?? I definitely wouldn’t apologize to her if I were you.

Worldly-Computer-962 − NTA, you, her step-child(but also not really for reasons we all know), are not at all obligated to be her emotional pillar.. The fact that she's trying to use you that way is creepy and weird.

Ok_Play2364 − I worked with a man in his late 50's like that. He never divorced his wife, but was in a long term relationship with a woman he lovingly referred to as the

[Reddit User] − NTA You don't owe her anything. She should talk to her partner about it or a therapist. I once dated a guy who admitted very late that he was still married. That was it for me. Not your circus.

Elladuskk − NTA. She’s being wildly inappropriate. She knew the deal, and now she’s whining to you? Nah. You told the truth. She needs to deal.

USCSS_Nostromo7 − Tell your dad if she asks you again you'll just start recommending her to leave your dad if she's so upset. Maybe then he'll tell her to back off.

IrisGalee − NTA. She’s crossing boundaries. She knew what she signed up for. U set ur boundaries, she ignored them. She got what she deserved.

FryOneFatManic − NTA. You were right in telling her she knew the situation when she got into it.

In conclusion, while family dynamics can be complex and layered, the author is not the asshole here. He was well within his rights to set boundaries and refuse to act as an emotional sponge for his dad’s partner, who was aware from the beginning of the complexities involved. Not every complaint requires an audience—and sometimes, protecting one’s own mental space must take priority over smoothing out someone else’s issues.

What do you think? Is it reasonable to expect a family member, especially an adult who had no part in creating the situation, to act as a sounding board for someone else’s emotional grievances? Or should boundaries simply be respected? Share your thoughts and join the discussion below.
