Why hasn't he asked me to be his girlfriend yet? And what should I do?

Anonymous
Well I've known this guy for 3 months now... He broke up with his girlfriend a month ago and my boyfriend and I broke up 3 weeks ago.. We've been talking or awhile now an have been talking more since I'm single. we've also hung out a few times and we've had sex already. I old him that I do want to get to know him better and he said he really does too. I asked him how are we gonna know if this is going anywhere an he told me that he didn't really want a girlfriend right now Because of where he's gonna be the next few years... But he said that who knows we might just click and might as well try because if you don't nothing will come of it. So I've told him that I like him many times and we've been hanging out a lot... Supper movies etc.. And he drove me home from school all of this week. He's also said he likes me. But I don't know why he hasn't asked me to be his girlfriend yet. I'm at the point where I want him to myself and being his girlfriend would be the answer. Its been about a week or 2 since I've talked to him bout relationship stuff. I don't know What to do? Any ideas? How long should I wait?
