I asked a guy to a movie recently. He said yes and we had a good time. Since then, he's been more friendly around me in school, but he hasn't asked me to go out again. I know that he's a bit shy when it comes to girls but since I asked him to the movie, shouldn't he know that I like him? And if he was interested wouldn't he do something about it? I don't know whether to give up or ask him out a second time.
