People who have decided against having their own children: what would it take to change your mind?

The love of my life at the time, my ex-wife, persuaded me to do it. The experience was mostly what I had anticipated, and I realised I was through after one. She wasn’t, which led to divorce. It’s an odd cognitive dissonance to experience because, while I genuinely care for and love my kid, I also kind of feel deep down that I should have abstained from having children.
