Someone's been naughty and there's a better than average chance that someone lives in a Missouri city that was just named as one of the top 5 most unfaithful places in America.

My Dating Advisor has created what they are calling the "Infidelity Index" using US census data to figure out the marriage, separation and divorce rates for 200 major US cities. They've combined that with Google data for which residents are doing searches that have to do with interests in affairs to compile this list of notoriously unfaithful cities.

With all those numbers crunched, one Missouri city comes up at nearly the top of this list for unfaithfulness. That city is...*drum roll*…St. Louis at #4 as one of the most cheating places in America. Congrats.

Why St. Louis for relationships behaving badly? St. Louis has a 47% marriage rate, a 9% divorce rate and a separation rate of 2%. The damning statistic though is the more than 30% Google search rate for affairs. Naughty, naughty.

For what it's worth, the other top 3 cities for unfaithfulness are in Texas. I blame the Dallas Cowboy Cheerleaders. Kidding.

It's not all dark clouds and bad news though. The top 4 most "faithful" cities are in California. Right. My theory is that they don't just search for information about affairs on Google, but rather just go out and do bad things. Hey, it's just a theory.

Check out the My Dating Advisor data for yourself. Just maybe don't plan a romantic weekend with your significant other in St. Louis if you plan to stay together.
