These Texas cities are where people are most likely to cheat, according to a study of 200 metro areas by MyDatingAdviser.com: Dallas (ranked No. 1 most unfaithful in the nation), Fort Worth (2nd), Houston (3rd), Plano (26th), Austin (44th) and Arlington (45th).

When it comes to sex and relationships, cheating can happen. The matchmaking experts at MyDatingAdviser.com put together a list of who cheats, and the results are pretty fascinating.

Everyone may have slightly different definitions for cheating — for example, does flirting under an IG picture or with a hot co-worker count? But there are a few acts or moves people universally consider cheating because they cross the lines of emotional and romantic intimacy: cuddling, spooning, kissing, getting emotionally close with someone you're attracted to, and of course, intercourse of any kind.

Sometimes, cheating happens because of someone's temperament or trouble with trusting in relationships. Other times, infidelity is born out of resentment toward your partner, disappointment that your needs aren't being met, or boredom. Cheating happens because you've fallen out of love, where you find yourself feeling more like friends who happen to have sex than partners. Or maybe you're just not attracted to your partner anymore.

Or maybe, you or your partner were unfaithful thanks to the city you're living in. No matter which side of it you're on, infidelity hurts. And looking at MyDatingAdviser.com Infidelity Hotlist, these cities have a lot of healing to do.

Amy Pritchett, Editor-in-Chief at MyDatingAdviser.com, said:

“Using data from the U.S. Census Bureau, we calculated something that we’ve dubbed the Infidelity Index for 200 major U.S. cities.

“The study factored in the population’s relationship satisfaction by looking at marriage, divorce, and separation rates. In addition, the population’s life satisfaction by evaluating emotional and physical well-being, work environment, and community. We also looked at the number of venues to meet for an affair, and the volume of searches on Google for affair hookup websites was also considered for the rankings.”

“While most would assume that bigger cities probably produce more cheaters per capita, this data shows us what we were already aware of; cheaters are everywhere, and infidelity can happen anywhere - in large cities and small ones.

It’s not singular to Florida, nor is it removed from quieter states like Pennsylvania or Arizona. And for what it’s worth, cheating comes in many forms and may look different for one person than it would for another. It can happen in marriages, emotionally, and just because of sudden circumstances…that have little to do with that person’s current relationship.”

7 surprising signs your spouse might be cheating

Changes in communication. A communication breakdown is never a positive sign. If you can't get your spouse to communicate (or even fight) with you, they no longer share their day with you, or the words "I love you" are no longer spoken, there's likely an underlying issue.

Appearance and hobbies. Indeed, taking care of yourself and devoting yourself to new hobbies and passions or even your work can be positive. Still, when combined with other suspicious behaviors, the following changes may cause concern.

Attitude changes. Your spouse may experience work stress or problems with other relationships that can lead to changes in attitude.

Lying and avoidance. Dishonesty in a marriage is a red flag.

Indifference. When your spouse shows apathy or lack of interest in things they used to love, communicate with them to see if there is another reason for the change in engagement. But if you also suspect infidelity, these changes may further indicate an affair.

Changes in your sex life. It is not uncommon for fluctuations in the frequency of sex in your marriage. But these signs may indicate the possibility of an affair.

A change in technology use. Infidelity is often revealed online, in text messages, or in phone messages. These tech changes may warrant concern.

Methodology:

To determine the most unfaithful cities in the nation, MyDatingAdviser.com compared 200 of the largest metro areas across four categories: 1) Relationship Satisfaction, 2) Life Satisfaction, 3) Cheating Intent, and 4) Affair Activities.

They then evaluated each area using nine data points of cheating friendliness. These data points included statistics such as the divorce rate, separation rate, number of cafes and bars, and how often people search for ‘Ashley Madison’ on Google (an online dating website for affairs).
