Surprised it didn't happen sooner, although he's probably been cheating on her for years.
Kind of rich and kind of famous homely guys like that are never content with their homely wives.
It was probably one of those things where he was fine with the companionship but wanted to **** hot young 37 year old Sonic Youth fans. And she was the antisex even before menopause. Sorry, but life is too short to be ****ing just one slot.
If they aren't mature enough for an open marriage, it's probably for the best they broke up.
