In 2002's Unfaithful Diane Lane meets a handsome Frenchman in a Hollywood-contrived New York City rainstorm, becomes infatuated and initiates a lurid (and oh-my-God-hot) affair.

But not before her husband Richard Gere finds out, confronts the lover and murders him, neatly disposing of his body in broad-daylight.

Mira Kirshenbaum, psychologist, relationship expert and author of the recently published When Good People Cheat: Inside the Hearts and Minds of People in Two Relationships says, "if you have ended an affair and made a decision to return to your marriage and work on it, it is a mistake to tell your spouse that you've cheated."

If nothing in your relationship is going to change as a result of an affair, if you plan to go back and be the best possible girlfriend you can be, what's the point of effing up a good thing? But Kirshenbaum's affirmation is nevertheless comforting: "All it would accomplish is adding a boatload of anger and mistrust to an already iffy relationship." Well said.
