K, I have a love related question...

So I like this guy who I'm just vrienden with right now...we don't go to the same school and I don't see him that much but I emai him all the time...the problem is I think he likes somebody else...
I wanted him to ask me to dance at the school homecoming but he didn't...he danced with somebody else and I can't tell if he likes me of not but I don't think he does...and according to my vrienden they think it's really obvious that I like him
So the point is how do I get him to know that I like him so he might actually like me???
And I dunno why but when he's around I get a little crazy :) lol
