I've liked this guy for about 3 years now and in January of last year
 we were really close like I would txt him everyday and I would tell
 him everything. we would talk about my day and he'd help me with
 problems I had and he was always really supportive of me and everything
 but in February he got his first girlfriend and when he told me it
 hurt really bad because he had me thinking that we had something
 together because 2 days before he got his girlfriend he told me he
 loved me and that really meant something to me and it hurt to see him
 with someone else. But we ended up not talking as much as we used to
 but we still talked and he would tell me stuff about his girlfriend
 and how she broke his heart when she was sexting and I couldn't help but feel bad for him when he told me all the things that she was
 putting him through but he finally broke up with her and he has had
 two other girlfriends since then and I don't know what's happened
 between us but he just won't talk to me and he tries to avoid sitting
 beside me and he tells my friend stuff about me and how he doesn’t like me and how I don't appeal to him as a friend and it hurts to hear him say that but no matter what he says about me or how much he hurts me I
 just can't seem to stop loving him. I just don’t know what to do when he stands right in front of me and kisses his girlfriend; I mean he knows that I still like him but he does it anyway. I just don't know what to do; can you help me?
