Part of me realizes that relationships take work and sacrifice and that if I just try it can work.  But another part of me feels like I'm the one making all the sacrifices and it's too much work for me and I'm just going to get hurt and he doesn't treat me right anyway.  

But it doesn't help that every time I try to quit him I miss him and regret it, and that no other guys at my college are appealing to me.
