Help!! the guy I thought wasn't into me asked me to be his girl?!?

HE LIKES YOU. That's a given. I've been in a situation just like this. And you like him so say YES. The whole girl thing with the movie..he could be making it up to make you jealous? This same thing has happened to me. You should just ask him about it. And obviously he cares about you and this other girl is probably not even on his mind. Believe me. You're probably the first and last one he thinks about when he goes to sleep at night.
