I don't agree with your assumptions. Prager travels around a lot. His wife may simply be getting tired of it and wanted him to stay home with her. It will be a friendly divorce. I knew a guy like that who flew around all the time for business reasons. He finally got tired of it and stayed put in a different job and re-married his former wife and kids. All a woman wants is a man to be with her. All these business/media/political jobs cause divorces left and right.
You could be right. But then why wouldn't they come up with some compromise for the 4 or so years their teen is still at home?
