Listen man, I have been in this situation. I met a girl was madly in love with her. Then all the sudden she changed and started hurting me on a regular basis. Long story short, we broke up she moved away. I was devistated, started drinking too much, and couldn't understand why she did it. And I like you thought well in a couple of years we will bump into each other and she will realize what she gave up. But its not worth it. You need to step totally away from the situation, and do whatever you have to do to get over her as soon as possible. Once I was over her and started getting my act back together, I met the real love of my life. We are now married, have a home together, and have two beautiful kids. And we are absolutely crazy about each other to this day. Quit sulking and get over her, you will find something fantastic someday!
