Aibu to think boyfriend was with his brothers girlfriend?

[erinS93]

So does anyone else find this odd? I’ve been with my partner a year. And I haven’t met his brother. He told me a story of how they randomly stopped speakin and don’t even have each other on any social media anymore and how they where really really close etc. my boyfriend told me he is nearly sure his brother slept with his ex wife. (My boyfriend and his ex wife have been split for 3 years) he told me how they used to go out all the time and there was one time he seen a picture of his ex’s boobs in his brothers phone. So he said she obviously sent the brother that. But then I’m over thinking that the reason that they don’t speak is something to do with my boyfriend sleeping with his brothers girlfriend? He maybe done it on badness if he thinks he was with his ex wife. Aibu to overthink this? Aibu

Your boyfriend doesn't speak to his brother, who he used to be close to. Your boyfriend thinks his brother may have slept with the bf's ex-wife. You are now wondering if your bf may have slept with his brother's girlfriend despite not having any evidence of this? I think you should split up.

Without knowing the actual circumstances of how they may have ended up in bed I personally wouldn't judge but its up to you. You know him, I don't.

I think the ops bf should run. Why would she even think that, given whst he's said about the brother. His comment on the brothers of is that she was nice...so the op assums they were shagging

People are saying it doesn’t matter as you’ve given no evidence for why you think that’s what happened. It’s like you’re just making a story up.
