By some coincidence, in my short life I've known a LOT of divorced men...(mainly as close friends...but no THAT kind of close).
Anyway, I'd say that for about 80% of all the cases, the story was this:
They meet a nice attractive young lady and get married. By the time they get round to divorcing things are like this: Wife is now fat, whinges, critises man, doesn't wear make up, and so on.
Then they complain that men take them for granted.
Just wondered if anyone has any ideas on this......
