Should I ask him what happened or just act unaffected?

I had been hanging out with a guy that I like a lot and there is amazing chemistry between us. I love that even more than the physical stuff, we can talk for hours about everything. Anyway, after hanging out several times and even after he spent the night, HE started asking me what I thought about us doing the whole dating thing. He even aske me if it was OK for him to grow his beard out (he's an actor and needed it for a role).

Now, immediately after that, several things happened. He moved (same city still), got sick, hosted out of town guests, started a new job, and then we got into all the holiday stuff., He hasn't asked me out in almost 2 months now. We still see each other around town occasionally and he still kisses and hugs me when we see each other.

My question is, should I ask him what happened or just accept that he simply doesn't have the feelings for me that he might once have had? I've known guys that try to pull stuff like this before you sleep with them, but not when you wake up in their arms.
