I'm with Squirt as always!
There's no compromise on this issue - either you want kids or you don't and if your partner feels differently it's not going to work. I am at the other end of the spectrum - I cannot wait to get married and have a family but there are some nice guys out there I won't date because they are alredy done with family dreams.
Of course you put that you don't THINK you really want kids so it sounds like you may still be considering the option. You need to look at your motivation for not wanting kids and try to determine if it is something you want to make a stand on or something that just works for you right now.
Good Luck!
