When i was 32 my H told me he had changed his mind and didn't want kids. We had been together 11 years. I had a choice - stay and have no dc or go and risk not finding anyone. I moved out within 2 months and met now DH at work and started a relationship immediately. I was clear i wanted marriage and kids from the beginning. i had ds1 at 35. ds2 at 37 and dd1 at 39.
My advice would be don't be too choosy. I don't mean settle for someone you hate. But, i have worked with single women who really want everything and moan about being single but aren't prepared to compromise at all.
Both dh and I wanted children and discussed the possibility of it not working out and how we would manage that. We decided having dc together and maybe divorcing later on wasn't the end of the world as having the children was the priority for us. We do love each other. but i think we are not a perfect match and if i'd been waiting for that i wouldn't have any children.
