I can also relate to your feelings.

I'm still single at 60+, no kids. For most of my life I've experienced disappointment. A dominating mother who thought she could demand that I produced a grandchild. I wasn't with anyone at the time (age 25). Various family members have their own opinions which, for some strange reason, they never share with me.

I did have a long relationship but that ended. I've stopped wondering if we'd still be together if we'd had kids.

There was a time when I was asked frequently why I'd never married. My stock answer was because I'd never found the right person. The latest put-down has been from my aunt. Her comment, when discussing my male friendships, "problem is you're too clever".

Main thing I learned was to never add pressure, it will either happen or not. It may take until late in life to achieve.
