I don't think he's that into me

I'm going a little crazy over here.  I've never been very good at game playing or, more accurately, "playing it cool."  When C and I went out the other night (and the couple of other nights as well) it seemed like he liked me.  He was affectionate and initiated kissing.  We had all that fairly deep conversation at the bar.  But then we separate and I get very very little positive reassurance.  We texted a little last night at my initiation.  Then tonight he texts at like 9:30 and says this week will be long days for him.  Fine, thanks for letting me know.  I ask if it's because of this campaign he's working on and he said yes, that and other things like a meeting tomorrow, etc., and he asked how I was doing.  I said okay, but a little sad and I had just gotten back from my adoption class.  He asked about the sadness - whether it was a mix of thoughts and feelings, so (and this may be the part where I didn't "play the game" right) I said it might be hormonal ha, and because of the ongoing transition, and because of the feeling of intimacy between us and then separation.  I was being real.  That's the truth... I kind of miss him and think of him and when you are close with someone as far as making out, I don't think it's strange to feel some connection/attachment.  But apparently I'm not supposed to admit that or something.  I don't know because his next text *completely* ignored that part of what I had said.  He basically said sorry, and he hopes I feel better or some stupid-a$$ thing like that.  Clearly, I'm a little vulnerable and sad feeling and it's converting to anger.  Anyway, fine, so he's not that into me - maybe a little into me but seemingly not a lot.  So what do I do?  Just try and forget about him?  Ugh.  Stupid dating.
