For the past year I have had a slowly forming crush on a boy in my grade. He is very popular, but has never dated because people are shallow or don't see him that way. I'm not terribly popular, but I am well-known, I have dated around and I know boys like me. I began to like this boy, but sort of ignored my feelings because I thought our looks didn't match (very immature I know). But then my mind sort of forced me to confront these feelings because he showed up in my dreams a lot (like A LOT!) and he just always found a way to creep into my thoughts. So I admitted to myself that I liked him. I asked him to prom, he said yes. I told him I liked him, he said he was flattered. He continues to talk to me like nothing happened. We got drunk and kissed a bit (his first kiss hehe), but we didn't even talk about the fact that it happened. He continues to talk to me like nothing happened.

Does he like me or is he just shy?

He liked you well enough to talk to you, and invite you to the prom.
