Help!

Warning: my head is spinning.

I'm making progress with this guy. He's the one I've been into forever and I'm head over heels for him. We spent some time together yesterday, talking and cuddling. It was really fun, really comfortable. And he kissed me, just on the cheek. I'm sorry to report that I had an attack of the butterflies and didn't just turn and kiss him back for real like I probably should have... but anyway, it wasn't awkward or anything and we were together for like an hour after that and things were okay.

But today, he seems to have totally pulled back. Except he seems like he's in a better mood than he was before. But... well, he's not all over me, wanting to know when he can see me again, etc. etc., which is what I WISH he was doing. Is it even slightly reasonable to expect that, or am I being, as I think, irrational and impatient?

Oh, I don't know what to think. And I only see him once a week or so because we live some distance away, and I'm not sure that I'll have a chance to see him again to make my intentions as perfectly clear as I'd like.

And how do I make intentions clear? Flirt hardcore? Say it flat out? Pin him against a wall and kiss him senseless? (Somehow I think that would be awkward if he wasn't expecting or wanting anything quite that forward...)

But if he's withdrawing slightly, is now the time to make my intentions clear? Or is now the time to play flirtation games? Or...

I just don't know. Insight? Please? I'm desperate, inexperienced, and trapped in my own head. I like him too much to think straight.
