Even with all that this family has going for them - the fame, the money, the...well, EVERYTHING it seems...they struggle like the rest of us to make their marriage work.

Sure, they probably don't squabble about who needs to take out the trash two times a week (let me just go on record here saying - NOT IT!!) - but clearly there were problems there. Sure, every marriage has issues - which are often magnified by money or fame - but what makes a partner turn to infidelity? Especially the kind that stretches over several decades and leaves innocent children reeling in its wake?

More importantly...how can one miss the signs? Or, do we simply choose to ignore what's in plain sight?

Listen, my seminars on Detecting Deception are always sellouts for a reason. People lie. People cheat. People steal. And they do it in intimate relationships, at work, online - there really is no end. And those they leave behind are damaged, perhaps forever, because of their dishonesty.

Many of us have been cheated on? You remember how that felt...devastating...heartbreaking...like you couldn't breathe. And you probably can recall in excruciating detail every moment of your recovery. Add 25 years and 4 kids (or 5+ depending on which report you believe) to that - and the effects are immeasurable.

So....what can we do to protect ourselves from this type of emotional damage?

When you think that the average person lies in 20% of their social interactions (J Pers Social Psychology. 1996) - and that marital infidelity is on a steep rise to Cheaterville, causing 50% of all divorces (Kinsey Institute, 2010) - and that straying among married men over 60 has doubled, tripled for women (NY Times, 2008) - it becomes clear that it's time to get educated on the ways in which we can spot deception in our lives.

Detecting deception is not as clear cut or easy as it may appear. No, their pants don't catch fire when a lie pops out...there are no noses growing 4 feet long...and shifty eyes alone (while annoying), don't necessarily mean your spouse is a low down, dirty liar.

And there may not be any concrete signs of infidelity - what you have to work with may be much less quantitative. While there may not be any lipstick on the collar, or receipts from the Holiday Inn laying around - there are clues left along the trail of any deceptive act or statement.

There are several methods we can employ that will help us identify "hot spots" in conversations or situations - moments in which you need to sit up, take notice and ask further questions. Much like Maria, if you have to confront your spouse with your suspicions, you'd better be on you're A-game - these variations occur quite quickly, and you have to be ready to pounce.

SHIFTY EYES: For instance, I referenced "shifty eyes". Many people think that eye contact is the key to catching a liar in the act. Yes, the eyes are the window the one's soul - and therefore fraught with information, but we have to be careful not to assign meaning to an individual's behavior - rather, we have to interpret the meaning behind the actions.

If you are having a convo with the hubby, and his level of eye contact suddenly changes from his normal patterns of behavior - this indicates a problem. In the US, we tend to make direct eye contact in conversations roughly 60% of the time. If this is your mate's normal level, and all of a sudden it jumps to 80%, or plummets to 20% - well Houston, we have a problem. It could certainly mean that he is trying to hid something - or he has an eyelash in his contact - be sure to fully evaluate the situation before reaching a conclusion.

THE NOSE KNOWS: Here's another tidbit - liars often have the sudden urge to itch their noses. Why is this, you ask?

Well - the nose contains erectile tissue, and as lying has some of the same physiological effects as arousal (increased blood flow, intense heart rate ), it is common for the areas containing this tissue to engorge with blood - leaving them tingly and itchy.

So, if you are conversing with your wife, and when you get to the subject of her hot new (much younger) boss, and she starts rubbing away at that nose of hers - time to take note.

THE FIDGETERS: Many people are naturally jittery - they twirl their hair, they bite their nails, they tug on their earlobes. They may be anxious or working on a tough problem. In these cases, these "pacifiers" are just that - an instinctual way to pacify ones nerves or concentrate on the task at hand.

Where we notice that fibbers deviate is that the rate and intensity of their normal behaviors magnify. They will be in a constant state of motion, touching their hand to their arm, twirling hair, scratching their head, picking imaginary bugs off their scumbag arms.

In these instances, the "pacifiers" have morphed into "manipulators" - designed to detract your attention from the lie coming out of their mouth, buy them more time to formulate an answer, or decrease their own stress and anxiety.

Learning to pick up on the cues that indicate deception may help you from becoming the next victim of marital infidelity...or it may prevent you from hiring a questionable potential employee, or figure out if your teen is still on the straight and narrow.

It's not necessary to go all Colombo on everyone you meet - but it can certainly be helpful in certain situations, and under certain circumstances.

Sadly, marriages are wracked by unfaithfulness every day. Perhaps you can save yourself from being the next super couple that falls.
