What is with this guy?!?

i really like this guy, and although he is shy he gave me the gist that he likes me too. We went out clubbing last night and we got with each other, he stuck with me all night and walked me home etc. we text quite a lot, and today i text-ed him and he hasn't replied. I was going to wait for him to get hold of me but it was going so well i didn't think it mattered. What to do now?! (i'm pretty sure my kissing can't be that bad!)
