The kids topic is an important core value, and the way I see it, since it did come up on the first date, and he did find out that your views don't match his, it's better off that he ended it after the first date. Yes, there are guys out there (like myself) who will not pursue or continue with someone if they do not want to have children and a family in the future. It's a core value, I believe.

I love my girlfriend very much, we've known each other for almost two years, and she has flip flopped on wanting to have kids in the future. Mind you, she already has one, and she's always maintained that she wanted more kids in the future, until recently. I told her that if she does decide on not wanting any more kids, that we would end it. It's just a core value.
