Um. I can't tell whether my boyfriend likes me or not. (Yeah. U may be thinking well he's dating U so.)

I ask this because he's distant and when I try to talk to him he runs away. And all me friends keep telling me he has a reputation with girls and that he's a  f***boy. So I don't really know if he likes me if he's just playing around.
 [A lot of pass relationships with cheating and lying so....kind of had a bad past with guys.]
I don't know whether to listen to my heart or my head.
