wait, he asked you to go to the movies but he hasn't asked you out? You mean he just hasn't set a date or something? If that is the case, then you are being way to passive. You waited 5 months for him to ask you out and now that he has and showed his interests you still want him to do all the work? Just ask him 'when are you taking me out, b/c I am waiting.'
If he likes you and you like him and both of you know it. I think it's an obvious yes. He maybe nervous. Maybe you should just say hey I saw this movie commercial we should see it. Then based off the response id go from there.
