What should I do? I'm so confused?

[Britt]

This weekend, I volunteered with a group of people I have never met at a homeless shelter serving and packaging food. There is one guy in particular who when I first met him, I could tell there was something different about him. I was his partner for all of the stuff we were doing at the shelter and we were laughing and singing along to the radio together the whole time. I have been thanking him for stuff he said and how he was so nice to me on Facebook, so we've been chatting some. I was only with him for about 4 hours, but I felt a strong connection. I can tell he cares about me and I care about him, but here's where I'm confused. I think I like him as more than friends. He shares my same values and religion, we like the same music, we both listen to each other, we both care about each other, we laugh at the same stuff. I don't know how to tell if he likes me back or not, and I would just become better friends with him first, but hes a grade ahead of me so I don't see him much if at all at school. I don't know what to do and I keep hoping he will ask one of the other kids from the volunteer group for my number and text me, but he hasn't. ANY REALISTIC AND NOT MEAN OR RUDE ADVICE IS APPRECIATED AND NEEDED. PLEASE PLEASE HELP.
