I think that the kids issue is a major one, as in if one partner wants kids and the other doesn't, then it is more than enough to cause major resentment and tear the two of you apart. I know I couldn't be with someone who had to have kids as I'm not sure if I will be healthy enough to have my own and give them the best mom possible. If someone told me that they needed kids to be fulfilled, I would need to let them go. I think it is a bit selfish, perhaps egotistical to think that he should be enough for you and that you shouldn't want kids. I also think that kids should be wanted by both parents, not just one of them. This guy doesn't sound like he would be a good dad, even if he reluctantly agreed to give you a child.
