I understand. It’s not a judgment on ALL women who are single, as some are abusive or simply should never have asked the woman to get married.
That said, it’s a numbers game out there and that is a red flag.
And from my experience in Seattle, the single mothers I met were not like you.
Heck, I dated one and she ended up having another kid (not by me!) not that long afterwards. And she was SUPPOSED to have moved to Atlanta and entered JobCorps or something like that. Irresponsibility is what I saw in most of them.
But that generalized sentiment is not meant to be a reflection on the totality of single motherhood.
