There is this guy from my first year of High School who I became good friends. Now I don't know if he is gay, bi or straight because he would tell me about him watching straight porn and wanting to have sex n stuff he was really masculine, as am I. But he gave me mixed signals all the time, it made me mad cause we were close but I didn't really know he would be touchy and saw him staring me at times. Anyway that great year went by and I realized I liked him a lot but he moved so I was sad but maybe it was best even for me ( even though I never really forgot him) We talked a few times later on and now 3 years later I find out he is starting college and is going to same one as me and now I can't stop thinking about him. I'm more mature now and feel like I like this guy but I just want to forget him cause he's prob straight, I don't know how to just forget him and not have these emotions. What do u think?

If you don't know... play it safe and forget it. Viewing something with the prism of several years hindsight.. its easy to convince yourself something was there that never was there.

If there are not clear signals NOW from him... assume there won't be.
