how do you get over a guy who lives right next to you?

it was a stupid move to begin with when I moved into the same apartment complex as my boyfriend at the time. But I thought I would be safer and it'd be better cause I'd be closer to him. Well, I moved just around the corner from him. Then he moved to get a two bedroom so that he could have a roommate, and he moved right next to me. like, My apartment is 448, his is 447. His roommate's wall is my roommate's wall...

Well, we broke up about 7 months ago... yeah... I know, I feel pretty pathetic. But we didn't really stop seeing each other until January. He got a new girlfriend in February... I'm not over him, I always see his car, and yesterday I saw her at his car and felt really compelled to run into her with my car...

To get over him, I first tried to listen to music, got a little too into a singer who has a wife and kid. So to move away from that... I got into Marijuana... and now I feel like I"m obsessing over it and I don't want to. I don't like smoking alone because it makes me paranoid, but I did it yesterday just because of how bad I felt.

I don't want to be a pot-head

but I don't want to feel this pain anymore and I don't know how to make it go away, I can't move because I"m going to school, he's supposedly moving, but he's ****** lied before about it. How do you get over your ex when he lives right next to you?

I've tried hanging around other guys, but they just think I'm a piece of *** they can take. The only guy I felt remotely interested in started sexually harassing me. I don't talk to him anymore.

I've memorized my Ex's phone number, I can't get it out of my head. I've deleted it from my phone, I've deleted everything I can think of of his... and he's still not going away! I still think of him every god damn day... It's driving me insane!

::sigh::

... any suggestions?
