Similar here, I was raised in a big family except I was the youngest.  Nothing about it makes me want to have children.  I understand that some people had terrific family lives where their parents taught them all kinds of interpersonal skills and were nurturing, etc... but that was far from my experience and I don't have those things internalized to pass on.  I've gotten very good with my cat though, as a middle aged man and I'm nurturing to her, but she's far less demanding than a child or children and I can afford her much more easily.      I dated a lot previously and grew a lot as a person and had some peak experiences but had a lot of bad experiences with women who had hidden agendas, issues with dishonesty, cheating, gaslighting, etc... so I gave it up and now focus on my job, friends and hobbies and I'm more consistently  happy than I've ever been in my life overall.
