This sounds like a guy who wants a trophy wife but can't get one.
I happen to be one of those "trophy" wives, who married a man 23 years older than me 20 years ago.
I don't understand the bitterness in some of these stories, except maybe from some first wives. When I met my husband his first wife was dead, and it took awhile, but his kids love me today, and call on me when they need help, and they are closer to me than him.
I actually am enjoying grandkids his first wife missed out on, and I feel sorry that she didn't experience the joy they give me. His kids know I am here for them, and our home is their home as well as mine, they always know they are welcome here (I've worked hard to make them know this).
Back in the old days, when wives died early (often in childbirth), men married much younger women to help raise his kids, and often had more with the younger wife. My husband didn't have that problem, and his kids, although only a few years younger than me, know that I love them. And their kids are my pride and joy, I am a young grandma and we camp and fish together, they love me.
I have the best of worlds, never had to experience a labor pain, but have beautiful grandkids who are now my fishing partners.
