Most people fall in love with people they spend the most time with.
For me, those would be the same people who share my values, life goals and expectations with. They might not be identitical, but aligned enough to be compatible.
When my marriage broke down and I started dating again, I realised I didn't want to blend families so I made two choices - date but no serious relationships until my children were older and no dads of young children. And I stuck to it.
Does that mean I might have missed out on the absolute most perfect man for me just because he had young children? No. Because the fact he had young children would have made him not perfect for me.
I did briefly date a man with young children before I had that realisation, which is what made me realise I didn't want it because his parenting style, approach to a happy/good childhood, what he wanted his children's childhood to look like didn't align with what I wanted for my children. It wasn't better or worse, just different. But it wasn't compatible either.
So I stopped dating him. I have no idea whether or not I could have fallen in love with him. We were very compatible in other ways but I didn't wait to find out.
I actually find it quite surprising reading the thread that other women wouldn't think like this. Not specifically about children just spending time and continuing a relationship with someone who was incompatible with them.
But I don't think anyone is suggesting that anyone should share their life with someone they don't love just because they look good on paper either.
For me, and others apparently, it's more about having similar shared values and attitudes rather than lives being perfect.
