I'm stupid

Katelyn
The past four months I've liked this guy....... He pretended to like me back after I asked him out 2 times he asked me out 1 time along time ago. Deep down I really think that he did like me at once I'm friends with his friends and all. I think his friends changed his mind or something. He never has gave me a straight answer and I just feel stupid that I wasted that much time on him. I can't really get away from him though, he's in every single class of mine n we sit next to each other in one now it makes me so mad thinking about. How do I get him out of my mind or what should I do to make him want me or to make him mad, even if he does come running I don't want him after everything that he put me through he put to much stress on my life.
