That plain sucks.
It's a social problem among the American middle and upper-middle classes too. Or at least it used to be. I remember men getting successful, having affairs with younger women, and divorcing their wives. The men didn't rate the contributions of their wives. They didn't seem to care about the well being of minor children either.
I noticed this pattern throughout the '80's for whatever reason.
The divorce theoretically compensated the women when the court dissolved the marriage contract. The wives were financially harmed invariably from what I saw though.
Our neighbor went as far as buying a sports car, a Corvette, to drive his 20 years younger wife around in-- not a good look IMO but he must have thought so.
IMO this kind of behavior borders on the line of narcissism or crosses it.
My nextdoor neighbor had barely enough resources to eek out a living. She had to go back to work in her '60's. She had to take a low paying job at the mall. She didn't get a retirement.
I believe in civil divorce (I think people should definitely have the right to divorce).
It's ugly in practice though.
The legal system seemed stacked against the women. I'm taking about women who did everything they were "supposed to do" and had never cheated.
It can certainly be a painful, ugly mess when two people have been married for 20 or 30 years separate or divorce.
None of the men I knew of were involved with a spy (of course) but that in itself seems to be as common as dirt.
