I'm just a dude who made a great mistake by trying to love a girl who didn't like me back. Now I'm a guy who doesn't give a damn well thing that happens to her. For all of those people like me don't worry you don't need to be friends with an old crush because in the end they're going to treat you like a big fat pile of shit of at least that's how mine treated me. 
Good luck don't waste your time on them like I did mind
