So I had a thing with a guy that I really liked and things were going fine until all of a sudden he started backing off and not texting me not really interested in hanging out with me and it really hurt me and I told him that but he doesn't care because he's a jerk and it took me a while to relize but I feels like its to late because I think I'm in love with him I can't get him off my mind there's literally a physical pain that I feel in my chest. He pretty much played me and toyed around with my feelings which isn't cool at all but I don't know what to do or how to give my mind a break from thinking about him. Any advice? Thanks :)
