Guilty Of Infidelity? Why You Can Blame Your In-Laws

Love, Heartbreak

Remember those soul-curdling scenes where poor Ben Stiller weathers the tyranical tauntings of patriarch Robert De Niro in Meet The Parents? What about Jane Fonda's Mommie Dearest-like antics toward her son's wife-to-be Jennifer Lopez in Monster-In-Law?

Makes you shudder, right? Shutter enough to make anyone pencil-in an indefinite rain check on that dinner date with your significant other's family.

If those stories were real, and not Hollywood fiction, Ben Stiller and J.Lo would've been more likely to act on their wandering eye and commit infidelity.

According to a new study from The University of Iowa, a bad relationship with in-laws might make us more prone to infidelity. Indeed, Jack Byrnes' lie detector tests and Viola Fields' passive-aggressive comments about weight may have been the ammunition needed to splinter through the relationship and sabotage it ... Tiger Woods-style.

In other words, the study found that infidelity is less likely among couples who like each other's parents, which makes sense. It's even harder to expose a philandering slimebag when they've bonded over beer and baseball with Pops.

Other noteworthy news from the study? Don't hook-up with your hot friend and expect romance, flowers, and monogamy.

Of the 783 men and women polled:

  • Women who hooked up with friends were 44% more likely to have multiple partners.
  • Men who knocked boots with gal pals were 25% more likely to not commit to monogamy.

Perhaps those who sleep with friends are just naturally more promiscuous?

Also, not horribly surprising, men were more likely to cheat. 17% admitted to an indiscretion, compared to the fairer sex's more demure 5%.
