Man Says His Mother and Sister Still Keep in Touch with His Cheating Ex Girlfriend — Makes Him ‘Extremely Uncomfortable’

A man says he feels “uncomfortable” with his mother and sister staying in touch with his ex — who cheated on him with another guy — and he’s wondering if he’s overreacting.

The 28-year-old shared his story on the Reddit forum “Am I the A——?”, where users ask for advice on personal problems. He explained that he recently ended a two-year relationship with his live-in girlfriend after discovering she had cheated on him.

“I only found out because the guy she was cheating on me with learned about me and reached out, saying he had no idea she was seeing anyone, and that she had been lying to him too,” he added.

The man said he “immediately” broke up with her, and she moved out. He told his family they were no longer together but “didn’t go into specifics about what happened.”

Several months later, the man found out that his mother and younger sister were still talking to his ex.

“I thought that was incredibly weird behavior, so I confronted them about it, explained the breakup, and told them she cheated on me,” he said.

His mom and sister seemed “sympathetic” at first and promised they would “cut contact” with the ex. But at a recent family dinner, he discovered they were still in touch.

He said he “immediately got defensive” and told them it felt like they didn’t care about how much the woman hurt him. His mother replied, “she’s a grown woman and she can talk to whoever she wants,” while his sister accused him of being a “typical” controlling man.

The OP left the dinner and has not spoken to his mom or sister since.

“So AITAH for being extremely uncomfortable with this and thinking about cutting ties with them until they understand how weird it is?” he asked at the end of his post.

Reddit users responded, saying his feelings are valid.

“NTA,” one person wrote. “It’s strange for your mom and sister to stay in contact with your ex. You asked them to stop and explained why. They should respect that. Honestly, who would want to stay in touch with someone who cheated? The only reason to stay in contact with an ex is if you share a child.”

Another user said, “NTA. This is weird, especially since the ex cheated on you. They are making it worse by lying instead of discussing it. I would go low contact with them for now since they seem to be choosing the ex over you.”

Some even suggested cutting off contact completely. One commenter wrote, “Leave them alone until they come to you. No check-ins, birthday calls, or holidays. It’s hard, but boundaries are effective and teach lessons.”
