Ok, I was seeing a guy for two months, and we had sex, and at that time i didn't know that he has a girlfriend. I fell in love and I wanted to be with him and it was casual at the begining then when any other guy approached me he got jealous and I didn't know what to think anymore. When I found out that he has a girlfriend, I was shocked and saw him two times after that, and then I decided not to do this anymore. He and his girlfriend are in a long distance relationship, and see each other once a month. I am sad because I fell in love, but also I don't want to get involved in another relationship with two people. Last time we saw, he said that his relationship is at crossroads and I didn't understand that. Was he just using me?
