What Rob and RR said.
Congrats on finding someone you think is "the one."
I don't like kids and I currently say that I don't want kids.  I used to want them, but not so much anymore.  However it is something that is up for negotiation.  I mainly don't want kids anytime soon, I wouldn't write them off completely for my lifetime.  Maybe in 5-10 years I'll want kids.  I'll need to meet a great woman first, though, and that's what's holding me back at the moment.  
I also would like to reiterate the question RR asked: does he know just how you feel about kids and what's his response to your feelings?
