I have a crush on my friend and its destroying me?

Its a guy... we've been friends for about a year. He's 16 and i'm 17... I like him but i'm not sure if he like me back.. I thought he did, but soon realized he just a friendly guy(how he interacts with people) today I saw a girl waiting for him (it was end of the school day) he walked up to her and I awkwardly followed behind. He said hi to her in a giggly boyish voice(he never does to me) and then said sarcastically hi to me. I said hi back with a smile- sarcastically...it was too awkward. So I started to speed up my walking to leave them behind. I was crushed.. I really like him. We both have a lot in common(He want to be a screenwriter and I want to be a film editor) and we both met our parents (it was even awkward :o) How can I deal with is situation? Should I talk to him? Is it too soon? Is there a way not to crush on him?
