Sad that he's not got what he wanted.
I'm not so sad that he doesn't have a carer in his old age. And with that thinking, he'd likely have ended up alone anyway, because the children wouldn't want to be around him much!
But my sympathy goes to the women left looking after children their men disposed of, and the children, of whom I was one, who were disposed of while their fathers went and had a fun life.
I know of some older men who did manage to marry and have children late - late meaning after their reproductive years would have been over were they women. They were millionaires. One had a family castle in Europe. Wives were in their twenties who were beautiful and in equal parts not interested in a career and happy to bend to his will.
Men of regular means seem to not understand the thing that women of average looks learn early on: you don't have the benefits that can accrue to those who are above-average. That's not unfair or even the end of the world. And also it's not because the opposite sex are horrible. It's just how things are, so accept the reality and get on with it.
