well the story is i've been going out with my gf for about a year and a half and recently she has been talking to another guy in our city, in out university for that matter and the talking has gotten to the point that she'll ignore me for him the talk has also gotten rather riske, i'm getting upset about this and she won't talk to me about it she will just get defencive and mad, i don't know what to do, we've broken up once but she came back to me and told me how much she missed me and blah blah blah but she continues talking to this guy, any suggestions? i really want to be with her but i might have to leave her if it continues much longer
