I saw what happened to many of my male friends, none of whom were idiots, all of whom genuinely tried to make their marriages work, and most of whom were seriously damaged emotionally and financially by the divorces that their wives initiated. After that I concluded that it would be insane for a man NOT to plan for a divorce if he decided to marry. (You are right, this is very sad, glad you noticed.)
OTOH I do know one local guy who was divorced by his wife for what I thought were good reasons -- he is charming, but an alcoholic -- who explained to me that while his wife had every opportunity to destroy him in the divorce, she had not abused her power, but was reasonable and even kind. I was shocked. In my experience real women simply did not behave that way during and after a divorce. She was so exceptional that I now think of her as something of a saint.
I have noticed that almost everybody thinks he or she got screwed in the divorce. I can't remember anyone ever saying to me that he or she came out ahead in the divorce.
Frankly, noone I know got married looking to divorce. And I have never seen a divorce that didn't in the end rip up both parties.
