Crush help? I've liked him once before?

Last year my crush and I talked a lot during tri 1 and 2, and flirted during tri 3. Near the end of tri 3 we figured out that we liked eachother. This was around 2 days from the end of the school year. He didn't have a cell, but he had a home phone. So we exchanged numbers and we hugged on the last day, which is really kind of lame but it was cute. Oh yeah and that day we were taking big group pictures and his arm was around me when we were doing that. It was all "New-Crush-y". So then over the summer break we didn't talk much at all, except the occasional comment on my miniscule blog. Well, eventually that stopped too.

So then this year rolled along, and after 2 1/2 months of not talking to a "new crush" its kind of awkward. Tri 1 we didn't talk at all. Tri 2 we talked a little, random flirty comments that happened just about once a week. At the end of Tri 3 he got facebook, which was good, but we havn't had a real "sit down and talk to me" conversation. The only thing we have talked about on facebook is this thing my friend and I are planning and have been planning since the end of last year. Some dumb game night that includes him and another friend. :) Anyway!

This tri (Tri 3) we have started to flirt more and talk a lot more, but it's still kind of awkward. I'll look at him, and sometimes I'll catch him looking at me but not often because it's almost like he forces himself not to look at me. Now he is in my periods 2,3,4, and gym class and we talk in periods 4 and sometimes during gym. When we play against eachother (its been the volleyball unit) we get really intense and its really fun, but still its like he's just having fun with me, but I can tell he likes me at least a little bit.

So, my question is, what do *I* do to help reassure him that this time it wont get awkward or anything between us and we can actually make it work this time? Any suggestions appreciated.
