I am in love with my best friend. What do I do?!?

I have a huge problem. The little details seem pretty important to me, so please please please tell me your honest opinion on this! I am honestly in love with one of my best friends. He is always saying he is afraid of commitment, and does not want a girlfriend. But that statement really confuses me. He seems to treat me subtly different from his other female friends. Like when a group of us are just hanging out, and I get up to do something, he -always- asks me where I am going. He does not do that with the other girls in our group. We always get along so well and we talk to each other about everything. He also does that silly little grade school thing where he is slightly, yet playfully, mean to me every now and then. Like he is always telling me to shut up in a joking manner. It sounds stupid but he doesn't do that to any other girls. There are several other little things that he does that I cannot really explain, you'd just have to see them to understand. Just things like the looks that he gives me, which seem to be kindof exclusive; and the way that he reacts to the things that I say. For instance, if I tell him he looks nice, he will get kindof flustered like he doesn't know what to say (he does this alot when I compliment him). He never does this if anyone else compliments him, he just kindof smiles a bit and says "whatever" or something along those lines. I could be crazy, but I swear he feels something for me. The other day he drove all the way across town to see me in my dress before I went to a formal with my friend. My friend Ashley thinks that is significant. She says that most guys would just be like "send me a pic" or some crap. Ugh, I don't know what to do! I didn't think explaining this could be any weirder, but here it goes. To top it all off, he is an RA in my dorm. That means he is not allowed to date residents like me. He is usually very observant of rules, so I cannot help but wonder if maybe that is a strong deciding factor on whether or not he will tell me he likes me. But school is almost out and the week after, he is coming to my birthday party...he will no longer be my RA then. I have a really hopeful feeling that something will happen then, but who knows. Please give me your honest input. I don't want to fawn over him if there is no chance, and I sure as hell don't want to ruin our amazing friendship by telling him that I am in love with him if he doesn't feel the same. And I swear, I'm not just being dramatic and saying I love him like some attention-starved teenager. There are a ton of guys on campus that want to date me, but they are just not my guy. I honest-to-God love this kid. I think about him at least 10 times a day. I don't know if I can wait until my birthday to figure all of this out, or at least get some outside input. Thanks for your help...
