The point is, I don't think you knew that it's actually the woman who is more likely to leave a marriage.
I knew that just from knowing lots of people who have divorced. The man is sad, and the woman is glad she's free of the relationship. I've seen over and over and over again.
Divorces don't mostly happen because the man is a playboy. It's actually quite the opposite. The woman is more likely to have longings outside of the relationship that cause divorces. Men usually want to stay with it. Women are the ones' that, generally speaking, get itchy for someone else to the point of wanting to divorce. It's because men are more deeply bonded, by nature, in a marital relationship than women are.
