Really into this guy, but am I wasting my time?

So, i'm Gay and i'm 20. There's this guy that went to my highschool and I had a little crush on him but he wasn't out yet. Anyway, I ran into him at a club a weekish ago and he's out now. He's extremely attractive in my opinion. He's brilliant, witty, and his conversations have substance. He's also really sweet. Anyway, we were kinda flirting and I got his number. I texted him that night to let him know how much I enjoyed our conversation and he told me he agreed and that it was "sooo refreshing" getting to talk with me. SO anyway, I told him goodnight yadda yadda. Anyway a few days later I texted him and asked if he might be interested in going to a local gay beach with me (neither of us have been, so I figured it would be fun.) and he said he was down. So I told him that I wanted to go sometime this week (it was like tuesday when I said that) and his exact reply was "i'm pretty booked this week" ...so obviously that's kind of blunt. So I replied exactly "ohh...soo. when do you think you'd have a day off? ps. you can tell me if you're not interested in going, i think i'd survive ;)" ...Kind of giving him the option to let me down, but then he replied saying "haha. I would have said no alot sooner, ill let you know when i'm free :)))" .... Then after that, he sent me a friend request on facebook. Also, a mutual friend of ours is going with me to a club on sunday, and she sent me a text saying "see you sunday love, watch out for ___" ...I never told her anything about him and I talking, so i'm uming he did, because the two of them are close? Is that a good thing that he told her? Or do you think it was more like "...watch out for him, he'll break your heart" This is all fine and dandy but it's been a few days now and I still haven't heard from him. If I wasn't so attracted to him I wouldn't be thinking about it so much. But the truth is i've really never felt like this about a guy before. He's not like most of the gay guys i've come into contact with. He's really level headed, he comes from a nice supportive family, he has pion, ambitions and goals. He also told me that he wants to find someone who's willing to commit and be exclusive. Which is what I want too. He's a really good guy and I would love to take things further with him. But I just dooon't know what to think. He's really hard to read. Should I just take things slow and give him time, wait for him? If he doesn't contact me by next weekish should I hit him up? I don't know :(
