Confused

Ok, so there's this guy I like, and I've known him for like a year, and he's been starting to flirt with me. I don't want to make any moves, because maybe I'm getting mixed signals. I think that I think he's flirting because I'm emotionally messed up. I have no idea what to do. I have one person to talk about this to, but she doesn't know him. OMG. IDK!
