Homecoming Help...Please I Gotta Kno?

I think you should just wait. You would haveve misinterpreted his reaction to you not dancing. He just might've been slightly disappointed. If he likes you and is worth it, I wouldn't worry about not dancing being a problem with him. He'll still like you just the same. However, if he doesn't know you like him and you want something to happen with that, you might want to let him know. Nothing bad can happen if you know for sure that he likes you.
