Sorry, He's Tired Of Having Sex With You

Here's an example: a guy meets a terribly attractive nanny from Norland. This man is at the top of his field and possibly of mixed ethnicity. A colleague introduces them and it's lust at first sight. From there, they get married, pump out a couple kids and enjoy immense financial success. But the driven man possesses a substantial ego and wants to scale higher mountains and mount higher scallions and maybe the former nanny isn't as interesting now that she, ironically, is caring for kids that they made together. Maybe he's not super-keen to hearing about childrearing, interior design and fjords. Perhaps she isn't as turned on by green jackets and Buicks as she once was. So, he finds a string of women who are still excited by his drive and even though they can't hold a candle to his wife in terms of looks, he digs the novelty of fresh tail.

In no way does this excuse infidelity, but it ought to illuminate why certain relationships can't survive with foundations built on flesh. Read: Help! My Wife Hates Sex!
