My Crush

I have a crush on this boy and I told him that. He responded in a vague way and I'm trying to get a clear answer out of him. We still talk and stuff, but it kinda hurts(however wussy that may sound)knowing that I don't know what he feels. Any thoughts on what to do? I don't know how to bring it up again without freaking him out completely. He's a nice boy(and possibly one of my most decent crushes)and I still want to be friends if he doesn't like me. I don't know... I need some input.
