HEY! I like/ liked you!

Umm, hi! We havent't talked in so long, that i'm confused. People who know you better than me right now, say you changed.
They say you are not the quiet, smart guy but you are smart, quiet but sick minded?? I don't know!
I just want to tell you this because well I liked for like 5 years now.. and i really want to move on if i find out you have/ had no feelings for me at all!
Just help me out here will you?
