Why can't he leave his girlfriend for me?

No. Get away fast. I just got of the same situation like this except the guy said he didn't want to be with his girlfriend anymore but continues to live with her. Either way, he is still with his girlfriend and he is not going to leave her for you. He is just rying to have his cake and eat it too. Ask yourself this, if he leaves her for you, what makes you thnk he is not going to do the same thing to you? Besides you'd want a guy who is single and can really b there for you. But no girl, this guy is no good. He just want to use you for sex only and until he gets tired of you, he will go to the next girl. Get out before you ge hurt. I know I did. We deserve a guy who can b there totally for us and who is not taken. Dump him now.

If you can handle it emotionally to talk to him, I see no harm in it. But I would not under any circumstance talk to him about sex, liking him, giving ultimatums. Let him get to know you as a person and a human being and if he falls in love with you, he will come to you. At the same time, look for other guys to like, there are many out there. At your age 18-24 range, I am assuming he is too, he probably likes to see how many girls he can attract, an ego boost. No real feelings for anyone but himself. You don't "care" for one person and go behind their back and talk about wanting you, sex, etc. , if that is what you guys talk about.

If you want to end up getting hurt then go for it. He flat out told you he still cares for her, she is his girlfriend. Holding on to feelings for him will just get you hurt in the end. Find a single guy hun, that is my best advice. Let him go just because he wants to talk to you doesn't mean anything. If you are able to put your feelings aside and talk to him as strictly friends then go ahead, but anything else would be wrong and unhealthy for you in the long run. Good luck
