Crushed Crush?

Okay. I'm a girl. There's this boy. That somehow made me like him so bad to the point I'm stalking his Facebook everyday. But then, we both moved to different schools and now he's like, on the other side of the country. Du know, new place new friends, cute guys, but my mind always seem to drift back to him. The smallest things make me remember him like, for example, a couple walks Von and the lad opens the door for her. I'll just remember back when he used to do that and smile for no reason. I think it's getting to far. It's been like almost 6 months since the last we saw each other, but I feel like I won't ever get over him? Not exactly sure why I typed all this just wanted to get it off my chest maybe. How do I forget him?
