Women are to blame because they become less attractive as they age, or they get lazy, or the kids suck the energy out of them. I think in most countries, women who cheat are much more vulnerable to it having a negative impact on their life. I think many societies "force" women to be tied to men financially. If you have ever fallen truly in love, you know that you would never want the person you love to cheat on you. Just verbal abuse, contempt, and constant nagging to work harder. My wife often accused me of "cheating" since we married thirteen years ago. My wife and I have grown together, and our priorities and outlook are still quite inline with each other, but if someday we diverge significantly enough, I would not want to tie her to me out of some devotion to an outdated concept, nor would I want to be tied down for that same reason.
