What if i'm really crushing on a guy i barely know?

so i went on a camping trip with my school and everyone was around the fire and then ppl started to leave to their cabins and then it was just me and this guy and we both were hitting it off and he seemed so sweet nice and kind guy...i kinda started to...

like him and then the next morning he didnt even say a word to me and now im like crushing on him and that was the first time i meet and he doesnt even talk to me but when he was about to leave from school he said bye to me but im like crushing on him and one of my friends is friends with him and idk what to do

Well if her is ignoring you obviously he only spoke to you becos everyone else went bak to their cabins, so just chill out and see if he starts speaking to you again, if not then just forget him.

Maybe you should try to talk to him again sometime in school...
Hang out with your friend when shes hanging out with him and yeah maybe then you will get to know him a little better and he'll start liking you too.
Dont get your hopes up... just try it. =]
