It's an interesting theory. It's so easy to forget that we humans are animals and have desires and drives that have thousands of years of momentum behind them. From that link you provided, I was shocked that the leading cause given for divorce was adultery by the wife. Why is that? Is it because when a man commits adultery the wife doesn't leave as frequently as the man does? Or do women have more affairs? I would find that hard to believe.
If we're talking about evolutionary theory, I'd guess that a man could cheat on a wife but still stick around to help raise his child. But if a woman cheats (and it leads to pregnancy) then the man may refuse to raise another man's child, and he decides to leave. (Lions are a little harsher, and a new dominant male will actually kill cubs from the previous den leader!)
