AITA for accidentally telling my ex-bf’s mum that he’s married?

An amicable breakup turned complicated years later when a woman received a surprise call from her ex-boyfriend’s mother. The two had split after he came out as gay, and she even attended his wedding to his husband as a friend. Everything seemed settled—until the mother, unaware of any changes, casually asked about wedding plans.

What makes the story more complicated is the ex’s secret strategy: he had been maintaining the illusion that he and his ex were still together and engaged to shield his homophobic mother, who lives abroad and rarely contacts anyone. Caught off guard, the woman answered honestly, revealing the breakup and the marriage. The ex later confronted her, upset that she “outed” his life without warning. Now she wonders if honesty in an innocent conversation made her the bad guy.

‘AITA for accidentally telling my ex-bf’s mum that he’s married?’

The friendship remained strong long after the romantic relationship ended.

My (33F) ex (38M) and I broke up a few years ago. He came out as gay and we broke up very amicably. We still remain friends, and I attended...

An unexpected call from the ex’s mother caught everyone by surprise.

A few days ago, an unknown number called me. I looked it up, and turns out it’s my ex’s mum who I have not heard from in years. I picked...

I started chatting, and she asks me when we are planning to get married. I am so confused. I ask her who, what, when, just what?

She then asked me if we had broken up, and I said yes, many years ago, and that he’s now married to another man. She seemed shocked at this and...

The aftermath brought confrontation when the ex blamed his friend for the revelation.

My ex then called me and told me that I shouldn’t have told her that we were not together anymore and that he was married since his mum is h__ophobic,

and he was hiding everything from her by pretending we were still together and engaged (not difficult since she lives in another country and barely calls anyways).

I told him that he didn’t inform me and it was not my responsibility to hide everything from his mum, and he told me it was not my place to...

The ex placed his former partner in an impossible position by building a long-term deception without ever looping her in. Maintaining a fake ongoing engagement required her unwitting cooperation, yet he never disclosed the arrangement or asked for her discretion. When she answered a direct question from someone she hadn’t spoken to in years, her truthful response aligned with basic social norms—most people don’t lie to cover for others unless explicitly requested. The responsibility for managing family perceptions rests with the person living the secret, not with an uninformed ex.

At the same time, the mother’s questions provided clear signals that she was operating under outdated information. A more cautious reply—such as deflecting with “you should ask him directly”—might have avoided dropping the full truth in one go. The added detail about the marriage, while accurate, escalated the shock for someone already unprepared. This highlights how even well-intentioned honesty can cause collateral harm in sensitive family dynamics involving homophobia and cultural distance.

Overall, the broader perspective reveals the challenges of navigating coming-out processes when fear of rejection leads to elaborate cover stories. While the ex’s fear is valid, outsourcing secrecy to an ex without consent crosses into unfair territory. True support in such situations requires open communication, not assumptions that others will automatically protect the lie.

Here’s what people had to say to OP:

Most users place the blame squarely on the ex for failing to inform his friend about the ongoing deception.

Only-Breadfruit-6108 − NTA for being honest when you didn’t know he was telling lies

TopAd7154 − NTA. Your ex put you in an awful position. The blame for this fallout lies solely with him.

Adorable-Sell-8107 − If he had a scheme involving you, he kinda needed to inform you of it. NTA obviously.

MovieLazy6576 − NTA. If someone wants to use you as their cover they should let you know.

These commenters acknowledge the poster’s innocence but suggest a gentler or more evasive response might have been kinder given the clues.

Sea-Operation-6123 − You attended his wedding. Did you ask or ever wonder why his mother was not there?

SpecialProfile2697 − He put you in the middle without informing you. This is on him, not you. NTA

MamaPeaButter − NTA but at the same time you did have some clues based on her questions that she was unaware of the breakup, etc.

While still assigning primary fault to the ex, these comments gently advise that the mother’s questions were red flags signaling limited knowledge.

Cautious-Spinach-635 − Nta he should have cued you in

DistrictComplete7113 − NTA. You can't be expected to uphold a lie you didn't knew existed. And you are his ex not his PR manager.

This story shows how secrets built on incomplete communication can explode unexpectedly, pulling innocent people into family conflicts they never signed up for. While the ex’s fear of his mother’s reaction is understandable, the lack of warning left his friend blindsided and unfairly blamed.
