Why is my boyfriend so different now?

Ok, so here is the scoop... We've been dating almost a year, in the begging I wasn't even looking for a boyfriend, we were friends. He paid attention to every little detail about my likes and dislikes..and so on... So what won me over completely was that he was oh SO affectionate, the kisses, the caresses, completely catering to my emotions, he would stare into my eyes, talk to me about anything. I was in total awe that I had found someone that could make me feel the way he did.

So here's the ringer now after 10 months or so (this has actually been progressing over the last few) I have brought this up to him... and he says he has no excuse for why he's changed, just that he has "settled" into the relationship? He doesn't ever really have much to say...now it appears he's not much of a talker, and is almost not affectionate at all... well I take that back, except for when he's in the mood, and as soon as the sex is over.. bam.. cold door! I'm so confused.. please help!
