So I (22m) have been talking to a girl I met (22f). We’ve been talking for a few months one thing has led to another. Well I told her that I had deleted my social media because I have months ago. Well I haven’t been able to find out her last name and I haven’t just wanted to be weird. But I saw it on her ID card for her job the other day. So I went and made a Facebook and found her. Turns out that she is married it has been with this guy for five years. I now have the guys information and I’m debating whether or not to tell him. She knows that I know and I’ve talk to her a bit and she thinks that we are friends with benefits now. Should I tell him or just step aside and let it take it’s course?

Edit: I just sent him a message. Let see how this goes.

Edit2: I’m now blocked so I guess he was not okay with it.
