What should I do now?

So the guy I like knows I like him. Before he would usually flirt and tease me and he would even drop into my cles during his TA periods. Then he found out I like him. Apparently, he was smiling when he found out and he said "Are you serious?" and then everyday that week he started looking really good at school, like dressing really nice and everything. But, instead of hanging out where I normally do (same table as him) I've been avoiding him and I've been just working on choreography in the dance studio. I don't know what I'm going to do...is he going to ask me out or will it just be awkward?
