friends with benefits could turn into...something more serious?

So here's story:

This guy, my first kiss, my first serious relationship, this one i'm trying to get back together with, is well, my un-official 'friend with benefits' now.
We dated a year ago. Let's just say the relationship didn't last long due to the fact he ended up moving away for a few months, and the week he got back he broke up with me. We stayed friends, since we have a LOT in common (same favorite games, shows, ideas, etc), and a few months ago we started hanging out a whole lot more often, and ended up starting a sort of no way in particular serious relationship together. As in, we got a little drunk and ended up making out, etc, etc. A week later we pretty much do the same thing, this time we end up sleeping together.
The problem is that he keeps saying he doesn't want a commitment, I tell him I don't care, because all I really care about is being with him and making him happy. I get caught up in the whole moment and I at that moment, i don't care.
But I guess I really do =\
The last time we hung out we ended up watching a movie and holding hands. ^^ nothing else happened except snuggling.

So, i want to actually start a real relationship with him again. but i have a feeling he's not into the whole kind of thing...and i'm horribly afraid it'd ruin what we have now.

Fond memories of him are like this: on a party he had I was the one who ended up taking care of him when he was blind-striken drunk and hurling all over the place. When we were dating last year we did get a photo with santa together.

Am I just a crazy ex who can't give up on a relationship, or do i have some base to even try to ask him to make it into a commitment?

Jam it back in, in the dark.

we've only done it once, and besides that, we still hang out and have fun times outside of sexual things.
=\ so its not entirely about sex.

There's nowhere I can't reach.

we've been through relationships twice with eachother, once when i first met him (it was a shortlived one, mostly because i was young (like freshman in highschool) and quite fickle and didn't know him that well), and the other one started out...sort of how this is going. that one ended mostly because of space issues (he moved to florida for a few months, and he came back, and decided he suddenly didn't want to be in a relationship)

but i dunno. i'll talk to him ASAP about it :< at the least, i'm tired of being used.

This thing is sticky, and I don't like it. I don't appreciate it.

i just graduated high school, so the there's a four year gap between the first time we dated and now, and a 1.5 year gap between the second time... @_@

I am a dolphin, do you want me on your body?
