Wow. After reading all the responses, I feel like a pathetic loser for being so shy.
I apologize for not posting with an update in a while. After the holiday, my final exam, and the weekend, I forgot to post what happened. Well, I hate to disappoint, but nothing happened between him and me. I thought that maybe after the exam I'll say something since this is my last chance, but unfortunately, he left the exam early and I had one exam question left (which I got wrong anyway). Part of me was hoping he was waiting around by the stairs, but he wasn't. At first, I was annoyed with myself for not letting anything happen sooner. I kept thinking about it the whole way home on the nearly 2 hour train ride.
I never initially intended to do anything sexual with this guy. Yes, I'm a virgin and I'm proud of it. I know this will probably sound lame to some of you, but I'm saving myself for someone special and meaningful. It would've been nice if the cute boy was my someone special, but nothing happened and it's my fault that I didn't do anything.
Still there was a shred of me hoping for something to come of this. So once I got home after the exam, I went on facebook and found him

. I sent him a message asking him about where the lab grades were posted. I really wanted to know and everyone else has been asking around and no one seems to know. Anyhow, it was used to have a main reason for randomly messaging him, but I also asked him if I knew him from somewhere and that I remembered his face from somewhere. I didn't really, I just wanted to see what he would make of such a comment. Anyhow, I haven't gotten a reply yet...
I'm trying to get over him though. I don't want to be wasting my time pondering about what I should've done or could've done or what could be happening now. It sucks because I still am pondering...
In the end, I didn't come out of this whole experience friendless (well as in new friends since I had current friends with me in class).
The most unexpected thing happened, and it actually concerned a cute girl. There was a girl in my class that I saw everyday on the bus, in class, and in lecture. We never spoke except for holding the door for each other when walking in and out of buildings. Finally, on the very last day (the day of our final exam) she decided to talk to me. It was so bizzare because she was doing what I had failed to do with the cute guy. She introduced herself and did the whole "hey, you're in my class" and the small talk continued up until they told us to be quiet and take the exam. I feel like such an idiot because all this time I was thinking about what to do about the cute guy, there was a girl probably thinking the same things about me. Anyhow, it was nice to make a new friend out of this summer class experience. She actually does go to my university and is enrolled at my campus, so I'll probably see her again in the future. It's funny how fate works.
After rereading this post for edits, I realized I'm not going to regret that nothing came out of this. I made the mistake of not acting on his signals, and hopefully in the future, I'll remember to act before it is too late. I guess I didn't do anything because I have never been in such a situation. Sure, I've had hunches about girls in high school who've had a crush on me, but I've never ever in my life seen (or perhaps noticed) signs that a guy was noticing me.
My only hope is to look for these signs more often now that I finally noticed. I certainly am conscious who I am staring at, but you have to remember someone might be staring at you, too.
