My boyfriend of over a year cheated on me when he was in Miami for business in January of 2013. In June of 2013, I went through his Facebook (first time doing so) and found messages of him talking to one of his buddies about him cheating on me while there. I confronted him and he said they just kissed. Now, in Sept. 2013 he's admitting to having sex with that girl. He seemed remorseful but now seems annoyed with the way I'm dealing with it... Like bringing it up every time we argue or being upset for 'no reason' and just being quiet. He has now placed the blame on me that I actually was the one who cheated because I had a guy flirting with me through fb and when we had broken up, I had sex with this other guy. He says we should be even? I don't believe what I did was cheating and I also told him about it the second we got back together... Not 8 months later.
