Well I like this boy but he has a girlfriend, him and her have been together for a year but he didn't know I liked him but when he found out he was like I can't leave my girlfriend we been throw a lot but I really do like you, his girlfriend found out and she says it all my fault, is it my fault??

I have had that happen and no its not your fault at all... they guy is probably a jerk and he shouldn't have said anything to you about that; if he really liked you he would've broken up with his girlfriend to be with you so he is just trying to play you. If he does like you and not his girlfriend and you REALLY like him then make him choose and then you will find out what his actual game plan is.
