A Dilemma!!!

I have a dilemma and I need help dealing with this dilemma!!! Where do I begin...so there is this guy...you all 'know' about this guy because I stay referring to him in posts. Anway...I still like this guy. I don't want to like this guy, but I can't help liking this guy. Common sense tells me to forget about this guy, but something stronger than that won't allow me. What is wrong with me??? Ok, if that wasn't enough...here's my dilemma. This guy has a girlfriend...and of course I was not happy to learn about this relationship but I have tried to deal with it. I can't help but hope, wish, think that their relationship will end. Hoping that she is not the 'one' for him. I can only dream that one day soon he will tell me that he misses me and that his relationship with his girlfriend has come to an end. How awlful is that??? I can't believe that I would wish a relationship to be over. I've never been like that before (oh wait, there was this one time last year...but that relationship was not a guy I liked or anything...it was a guy that was dealing with my girl and I knew she could do better, so I kinda wished something would happen to end that mess...) I asked this guy the other day, "Are you happy?" He replied..."Im content...I don't get happy." That statement really upset me...because I truly want him to be happy. I guess that's just the type of person I am...I care about others well-being. As soon as he said that...my crazy thinking went to straight to thinking that one of the reasons he isn't happy is because he is with her...know that could be true...but who am I to think that. I don't know his girlfriend...so I shouldn't think that she is not a wonderful woman. She probably is wonderful and probably really cares for him...but I can't help thinking what I think. I want him to happy with her or with someone...of course I wish that someone was me...because I know I can make him happy. I shouldn't be so selfish...am I only thinking of myself??? I'm not even sure anymore. I would feel really stupid if I was sitting around and thinking about him and he didn't give a care about me...well I guess I should take the fact that he has a girlfriend and that girlfriend isn't me...that he doesn't care about me. But maybe, possibly, some way, some how...Im not the only one thinking about how good we could be together. Maybe I need counseling...maybe I should talk to him about this (but I can't, I'm too much of a punk)...Someone please help me!!! I am so horrible...I don't wish him bad...quite the opposite I wish him so much success, happiness, peace, and every other positive thing in life...I want his future to be better than he could ever imagine. He told me why we stopped dealing with each other...and honestly I was upset at that time and really don't remember what he said...but I do know...that I was willing to do what was necessary to have a successful relationship with him in the future. Maybe the girlfriend should be a sign to me...but she isn't and I don't know why. I understand that we aren't dealing and most likely won't ever deal...but... (SCREAMING!!!!!!)
