Don't listen to them. What you really need to do is serenade her with a romantic song from a boombox held above your head.
Stop being a pussy and be direct. If you don't you'll be forever in the land of "what ifs" and that's not fun. Just go and lay your heart out and talk. I'm not saying to yell it from the other side of the cafeteria, I'm saying have a chat outside or someplace quiet and work it out from there. If she is someone nice she won't be a bitch.
