Relationships & Dating

So I have had the biggest crush on a guy that works the concierge desk in the lobby of my apartment building. He's extremely good looking, very nice and sweet, and has a lot of ambition. We usually flirt a little bit when I walk by and say hi, nothing major. But last thursday, he helped me with some curtain issues in my apartment, even getting a maintenance guy to do it. When I was down there, I had my face half-hidden in my sweater (it was cold that day) and he goes "Stop doing that, its so cute....you're making this very hard for me." As I was leaving to go back to my apartment, he called out to me and came up and asked me to come by Sunday (today). So today, I spend pretty much the whole day at the internet cafe, which is all glass and is about 20 feet from the desk, so he was waving and smiling most of the time. At one point, he even came in to ask if I wanted anything from the store downstairs, and ended up buying me a soda. From time to time, I would go out and we would chat and flirt a little bit more. When he went out for a cigarette, I told him how much of a deal-breaker smoking was for me, and when he came back he goes "deal-breaker? There isn't even a deal...yet." We kept smiling at each other, and then I finally got bored of being in the lounge and went out to buy carpet cleaner, I came back we chatted a bit more, and then I went home. I know this isnt a lot of information to go on, but do you think he might like me? Enough to ask me out at some point? I haven't really expected him to ask me out or for my number yet since we don't really know each other, and he does work in my building. But I really like him, and I want to know how I can get to know him enough for him to get my number. Thanks!

btw, I'm 22, he's 25.
