I know there's no real logic behind any of it. My mother wasn't teaching me a life lesson, she was just feeling sorry for the family friend who found out she couldn't have children after all those years of wanting them. But in all the irrationality that exists in my head, that's what I took out of it.
My bf has also always wanted kids and I only told him this week about my worries on the topic. It was good to tell him. I think I subconsciously thought he would pack his bags and find someone with an abundance of fertility. My T would call it a distortion, apparently I'm good at them

. But he was really sweet about it saying that nowadays there's things we can try if we do have trouble at that time.
