Men & Women With These Personality Traits Are Most Likely To Be Caught Cheating In Marriages & Relationships

Unless you’re a fortune teller, when you're first dating someone, it’s almost impossible to know in advance if how likely they are to end up cheating on you in a marriage or long-term relationship.

If we could see acts of infidelity before they happened, we might make very different decisions about marriages and relationships altogether, and if nothing else, we wouldn't be shocked to find out our boyfriend, girlfriend, husband or wife has had an affair.

But it goes without saying that people with certain personality types are more likely to be caught cheating than others. It's something most of us understand intuitively, even if we can’t exactly explain it to anyone else, or even to ourselves.

Looking back after learning of an affair, many betrayed partners say things like, “I should have seen it coming.”

Taken together, these observations suggest an important truth that recent research has begun to corroborate.

Simply put, partners who exhibit certain dominant personality traits are more likely to cheat than others.

And although nothing can truly prepare you for the experience of a partner's infidelity, you can put your observations of your partner to good use if their behavior is, or later becomes, suspicious.

Here are seven personality traits commonly found in people who are caught cheating in marriages and romantic relationships.

1. Narcissism

Narcissism isn't an easy thing to define. Similarly, it can also be difficult to spot, especially during the early part of a relationship.

This isn't the place for a deep dive into the narcissistic personality type, but here are few markers to watch out for:

  • Egotistical
  • Self-absorbed
  • A lack of empathy
  • Manipulative

Being romantically involved with a true narcissist is something else entirely, but if your partner consistently displays the above traits, you should probably still be on your guard against the possibility of infidelity. It’s sad to say, but someone who’s this self-involved is capable of almost anything.

2. Flirtatiousness

Being attentive and charming is one thing, but persistent flirtatiousness can be a strong indicator of future infidelity. People who flirt a lot like to give and receive attention, sometimes at the expense of their partners’ feelings.

And while you probably shouldn't read too much into occasional flirting, it is something to be wary of if your relationship shows other signs of trouble.

3. Greediness

If your partner demonstrates greed in many of his or her dealings with others, it could be a sign of future infidelity. This is especially true if their greed is paired with a "grass is always greener on the other side" mentality.

These two qualities are unpleasant enough on their own. But when you find them merged within one person, they could comprise a disturbing tendency.

It’s an ugly truth to contend with, but some people believe they deserve more than others. The source of this sense of entitlement varies from person to person, but a partner who’s driven by greed is probably not a partner you should trust without justification.

4. Insecurity

While a certain amount of self-doubt is reasonable and healthy, a partner with deep insecurities can be a real problem.

This is especially true regarding infidelity. In most cases, deep feelings of insecurity stem from large reserves of pain, and unfortunately, some people are willing to cheat on their partner to soothe this pain for a while.

That’s why it’s wise to watch out if your partner is excessively insecure. Someone who remains hurt for long periods of time might not think twice about hurting you. All by itself, insecurity doesn't guarantee that your partner will be unfaithful. But it could be an indicator of future infidelity if it occurs in tandem with one or more of the other traits on our list.

5. Impulsiveness

A lack of impulse control is the hallmark of many cheating partners. Extremely impulsive people sometimes lack the discipline to make kind and loving choices. This may or may not be a reflection of their core morality, but impulse control can be an indicator of infidelity.

And remember, there’s a big difference between being ‘spontaneous’ and lacking impulse control.

The first is a fun, energetic quality to have, while the second can be a sign of pathology. But like many of the traits on our list, impulsivity doesn't guarantee infidelity all by itself.

6. Permissive toward infidelity

Some people have more libertine attitudes toward relationships than others. While the origins of these attitudes can be difficult to trace, a partner with a permissive stance toward infidelity might be cause for suspicion.

If this permissive attitude merely means your partner is non-judgmental, there might not be anything to worry about. But, if this permissive stance extends beyond the philosophical realm, it could be an indicator of infidelity.

Remember, people tell us who they are with their attitudes, words, and actions. For the purpose of self preservation, it’s always a good idea to listen to what your partner has to say.

7. Excessively suspicious

It’s an old saying that cheaters think everyone else is a cheater too.

If your partner constantly thinks you’re cheating on them, it could be a sign that they’re likely to be unfaithful themselves.

You should be especially careful if these suspicions arise out of nothing or become a dominant theme of your relationship. We all get jealous or suspicious at times, but neither of these are the defining traits of a healthy person. An honest partner won’t accuse you of being unfaithful because they don’t sense such deceitful tendencies floating around in their own heart.

Again, there are no guaranteed indicators of future infidelity.

This is an important fact to remember as you apply this new knowledge to your relationship.

Obviously, no one is perfect. Your partner is bound to exhibit a version of these traits at one time or another, but this doesn't mean they’re definitely going to cheat on you.

Regarding the possibility of cheating, the significance of these personality traits is always contextual. We’re all insecure, greedy, or impulsive at times, but if these traits are (or become) defining qualities of your partner, there might be trouble ahead.

Lastly, the worst case scenario is one in which your partner suddenly starts to manifest several of these traits simultaneously.

That’s when it might be time to start taking stock.
