silda wall blames herself for eliot spitzer's affair with a prostituteWhen it comes to infidelity, usually there's one thing everybody can agree on: It's the Other Woman's fault.

But the case of Eliot Spitzer, the former governor of New York busted for stepping out on his wife of 33 years with prostitute Ashley Dupre, is turning out to be one bizarre love triangle.

After his sordid affair was revealed, Spitzer, now better known as "Client 9," decided to lay low, apparently biding his time before a triumphant return to politics. Dupre milked her infamy and was born again as a sex-advice columnist.

Meanwhile, Silda Wall -- Spitzer's long-suffering wife -- got busy standing by her man. Now, according to a new book, "Rough Justice: The Rise and Fall of Eliot Spitzer," she's apparently blaming herself.

"The wife is supposed to take care of the sex. This is my failing; I wasn't adequate," Wall reportedly told author Peter Elkind.

Ex-squeeze us!? Last we heard, having sex is definitely one tenet of a healthy marriage, but if you're not knocking boots, you're pretty much both to blame. Besides, it's hardly an excuse for your husband to have unprotected sex with a hooker, then lie to you. Or, say, your three daughters.

But maybe we missed the memo being distributed at sex rehab.

What do you think: Does lackluster (or a lack of) sex give a guy the right to stray? Or are there other ways to resuscitate your love life? And what kind of woman doesn't at least give her husband half the credit for his bad behavior?
