Girls,help if u have boy experiance!HELP PLZ?

Ive asked a few questions about him already.I think this guy likes me and I like him back.He emails me, talks to me, IMs me,and tells me almost everything.I can see him look at through the corner of my eye. Yet he calls me noob and nerd n stuff but Im blond, tall, and pretty.Alot of my friends think he likes me and is gonna ask me out...he is also smart...Does he liike me or not?Does he just want to be friends?An I just overreacting and obsessing over a guy for no reason?DOES HE LIKE ME?
