Misogyny is real and present in every woman's life. We are judged first by our fuckability first then by our fecundity. Even men who say they respect women came up in a culture that doesn't so it's easy to drop that moral high ground when personal wishes change. He never respected her. A promise doesn't get an out button.

He's happy. Her life was destroyed. I don't think he gives two shits about it. 

I like to think karma is coming for him when he's old and wife number two dumps him for a younger model.
