I'm having a little dilemma at the moment regarding my long-term, long-distance boyfriend. We have been together over 3.5 years and living about an hour away from each other. Last weekend, I accidentally found out that while I was away for 2 weeks, he was sending text messages and flirting (X's and O's, checking up on her at 2-3am in the morning...) with a random girl, seems like he met earlier in a bar. When I confessed to him that I accidentally come across the messages as I thought it was sent to me and I just wanted to reminded myself of how sweet we were (I do that on my phone all the time), he said it was just "for a kick" and it didn't mean anything. I understand that flirting is not a big deal, but given that this girl he's met at a random place, and he has her number (he must have asked for it) and then contacted her as if she is one of his close acquaintance... I grow up in a very strict and well educated family and quite confused right now. I used to give him the benefit of the doubt and trust him to go out with his buddies and have fun at bars and clubs most Friday nights, now I am not so sure anymore. I have lost some trust in him and don't know if I should move on or if I stay, how can we carry on?
I very much appreciate your time and advice!
