Does he like me? best answer get 10 pts!!?

he notices me in school, talk to me when theres opportunity (but not all the time, he doesnt seem clingy), he say hi to me and smiles everytime we p by the hallways. he also added me in facebook. as of lately i've been talking to him on msn and i think we were flirting i am not sure. the conversation was long, interesting and im the first one who logged off first. he commented on my smile and how i could get away with it when i do something bad. he then thinks that we are adorable when i told him that gullible people are adorable... do you think i might have a shot with him? i might hint to him to go to the school dance with me...
