Girl problem

[StarBall18]

Well her is the situation. This girl and I have known each other for 3 or 4 years now. We started hanging out because we were attracted to each other. We stoped when i got a gf and she got a bf. Due to at the time her not being able to truthfully tell me how she felt so i went my seprete ways. This was in high school years ago know. I am a couple years out of school and she was younger and just graduate some time ago now. In the past couple years we have shared that we still have feeling for each other but we have bad timeing, evertime one of us has something else going on at the time or as it happened i left for college and she was still back at home. Now we are both going to school and stuff and have shared that we both still have feelings for each other, but she has a boyfriend right now and I dont know what to do about it. She has told me that i'm the only guy she can tell anything to and that im a great friend and stuff. But that she still has feelings for me but is confused about everything due to the fact she has been dating this other guy for sometime now. Who never really wants to hang out with her or do anything, likes drugs (he claimed he quit, but i dont think so). So Im wondering what everyone thinks that i should do about this situation. Should i just continue to be there for her whenever she needs me and wait to see if it goes my way or just scartch it and move on?
