How do I forget about a guy I don't even like? I know.. that sounds beyond stupid!

This guy used to constanly tell me that he liked me.. I never give him a chance because first I didn't like him and second I didn't feel that he was approaching me the right way.

The thing is that I don't see him very often anymore but every time I know from him he is still a sweet goofy guy that tells how much he likes me.. and that.. I don't know.. keeps me thiking about him a lot. But I honestly question myself about it and can come up with a list of things that I don't like about him and that would ruin any relationship we can have.

He's a good guy.. but I don't want a boyfriend..

I honestly think I have the answers just want to talk it out with somebody.. maybe someone can say "I understand".
