I agree with your post.... but I think, in many cases, it isn't "just" a physical reason for the split - but one where both quit trying. Whether it is because of other underlying problems, or just laziness - but when you forget to show excitement at being together, or stop the courtesies you used to show..... those little problems just pile on top of each other until there is a mountain between the two.

Yeah. You've got a point. I think that in some of the divorce cases I have had close personal access to, the couple married when they were young, relatively inexperienced with a lot of things, and had all kinds of expectations with limited realistic knowledge of how life and society works. When their high school and college mentality of mutual narcissism was challenged by realities of daily married life, they choked. Adultery in itself is not necessarily a reason to divorce, although I well understand why someone would seek that.

There's a girl I know (I say "a girl" but she's really 32) who has just burned through her third cohabiting "committed" sexual relationship. She's bitter, of course. But from her conversations with me I can kind of tell that some of her expectations are unrealistic. Maybe the guy was a creep, but there are always two sides to these stories. Some people don't know how to "make up" after arguments or major disagreements, but there are cases where some sort of separation is inevitable. Call it "The Woody Allen Syndrome." Or maybe The Henry the Eighth Syndrome. There are plenty of men who are bad news.

Widely divergent differences of opinion, taste, lifestyle, politics, or religion (in mid-life) can also be potent triggers. Look at Jane Fonda and Ted Turner! And when it's not sex,politics, and religion, money can rear its ugly head in the oddest and most demented ways.

I never figured out the real story with Lady Diana and Charles Windsor though. Classic age difference and personality clash, maybe?
