If you feel this strongly, then don't. There are men and women who are happy without having children. Be true to your standards.
I don't want children because i don't think i could handle it. I would love it to be different but i just can't see myself as a mother or handling 'motherhood' well. It would be unfair to have children if you are not willing to give up who you was for them.
I am 51 with no children. Fortunately the baby factory in me wasn't operable. I have two dogs and a husband. I like the freedom it provides. We moved into a motorhome to simplify our life together further.
Maybe you need to find women that have already raised their kids?
Then the woman you were dating was the problem... there are women out there that have raised their kids and are still young at heart and good women. Might be like finding a needle in a haystack, but yes, they exist.
For Pete's sake, if you don't want them, you do not have to have them, end of story.
