Should I forget him?

I am finding it hard to get over a certain guy. We were never friends and he was never that friendly to me and although we were in the same college classes he just used to blank me. Sometimes he would stare at me from afar but up close would blank me and not look at me. I drunkenly told him I fancied him on an email but he never replied so he can't feel the same can he? I just want to stop fancying him because he acted like that with me and ignored my email. Should I just forget him? Any ideas how? Answers are appreciated thanks xxx
