Guy I work with cheated on his wife with me. Do I tell her now or wait?
My (29F) co-worker (31M) hooked up with me for 3 months last year while he was engaged to someone. He never told me he was engaged. We worked in different departments for a huge company so I didn’t think our work paths would cross and that it’s just a hookup. He marries the woman a couple of months ago and tells me he was ‘on a break’ with her while we were hooking up but I then understand from mutual friends that that isn’t the case and that he’d actually cheated multiple times.
Since his marriage, he has unexpectedly been transferred to my work department. We work closely, need to send each other files, be on the same calls etc. I’ve been acting professional, just focusing on the work aspects. I might be transferring out of that department towards the end of the year anyway.
Should I tell the wife now that he’d cheated (potentially before they try conceiving if they’re thinking of that; she’s 33? I’d want to know if I was her) or do I wait until I move out of the team as I don’t want him to try to make it difficult for me to do my job?
Side note: I have proof of the hookups and dates that they’d occurred on, so she’d be able to track that I’m genuine.
