Why do people cheat in relationships and have affairs?

Infidelity happens for a wide variety of reasons, ranging from seeking ego gratification to taking revenge. To understand why people cheat, we need to understand why they get into relationships in the first place. A relationship is a type of contract that two individuals enter into. There are unwritten terms of this contract that either party is expected to follow.

For example, each party expects love, trust, and companionship from the other party.  In this sense, a relationship is not very different from a business contract. Just as a business partnership is entered into because it meets the needs of the parties involved; similarly, two people enter into a relationship to meet their needs of sexual and emotional gratification.

We can safely assume that when the needs of a person in a relationship are no longer being met, they would seek to leave. The important question is: Why do people- if they’re not satisfied in a relationship- cheat instead of ending the relationship altogether?

The simple answer is that the costs of ending a relationship entirely are too huge. For example, it may be harder for a woman to leave a man on whom she’s economically dependent. Similarly, it may harder for a man to leave a woman with whom he has had kids. So they walk on thin ice by having an affair and try to eat the cake and have it too.

Sex differences in the ways people cheat

Men mainly enter relationships for sex and women for love. Therefore, if men are not sexually satisfied and women are not emotionally satisfied in relationships, they have a motive to cheat. In surveys, women frequently cite ‘lack of emotional intimacy’ as the major reason for having an affair. 

Men dissatisfied in their relationships are more likely than women to use prostitution or escorts services and women's use of such services is rare. When women do use such services, they do so for reasons that are incomprehensible and inconceivable to men- to cuddle, to talk, to have a nice, romantic dinner or to simply lie down together without saying or doing anything.

Women are intuitive and know when love is absent in a relationship. This is why most break-ups are initiated by women.1 Women can initiate a break-up in the most complicated of ways and having an affair could be less about hooking up with the new person and more about getting out of the current relationship.

If a woman finds that an affair does not have the potential to become a lasting, emotional connection, she’s likely to quit. On the contrary, a man may not mind if he keeps getting sex from an affair and nothing else. While men are able to separate sex from love; to women, sex almost always equals love. 

This is why it is hard for a woman to comprehend how men are able to have sex and then say, “It meant nothing to me.” For women, the physical is strongly tied to the emotional.

Speaking from a purely reproductive standpoint, men have more to gain by seeking extra-pair copulations than women do.2 However, this does not mean that women cheat less often than men; only that if they get caught they have more to lose than men.


Other psychological reasons why people cheat

Whenever one tries to understand infidelity, the evolutionary psychological reasons as to why people engage in the behavior should be sought out first. In most cases, for infidelity to happen, the new mate should have more mate value than the previous mate, at least in the eyes of the person committing infidelity. 

For a man to cheat on his wife with a mistress, the latter usually has to be more attractive than the wife. For a woman to cheat on her husband, the new man has to be better than the husband in some way.

There are people who seem to be in perfect and happy relationships and yet cheat on their partners. Often, this has a lot to do a with a person’s own psychological makeup than either the relationship or the relationship partner. 

Take the classic example of a happily married man with an amazing wife and kids who stray because he no longer gets the attention of his wife who has now wrapped herself up in the kids. If the man suffered from a general lack of attention throughout his childhood, it is likely that he will cheat because retrieving lost attention is important to him.

Author Esther Perel gives a nice example of a woman who was ‘good’ all her life and believed she’d missed the ‘fun’ of teenage years. She risked her current, functional relationship to hook up with a man she would have never dated in normal circumstances. Through the affair, she was essentially trying to get back her lost teenage years by finally trying to be a person she never was. 

Our identities are closely tied to our behaviors. Cheating, in some cases, may happen because a person is dissatisfied with their current identity and wants to a try a new one or relive some old, cherished one such as being a teenager.

Body language: Gestures of the head and neck

The head nod
Nodding the head almost everywhere in the world means ‘Yes’ and shaking the head from side to side means ‘No’. A slight head nod is used as a greeting gesture, especially when two people greet each other from a distance. It sends the message, ‘Yes, I acknowledge you’.

Body language: The truth of the pointing foot

When we communicate with others, our attention is focused mainly on the words they speak and the facial expressions they make. We pay little, if any, attention to gestures of the body and when it comes to the feet, we almost never look at them.

Body language: Clenching and clasping of the hands

Clenching hands in front of the body
This gesture has three main positions: hands clenched in front of the face, hands clenched resting on the desk or lap and, while standing, hands clenched over the lower abdomen.

Body language: Crossing the arms

Crossing the arms across the chest is a classic gesture of defensiveness. This defensiveness usually manifests as uneasiness, shynessor insecurity.

Body language: Hands touching the head

Scratching the hair
When we scratch our hair using one or more fingers anywhere on top, back or side of the head, it signals the emotional state of confusion. Watch any student trying to solve a difficult problem and you are likely to observe this gesture. There isn't a better place to observe this gesture than an exam hall, where students often have no idea what the question paper is trying to say!

Body language: Hands touching the neck

Rubbing the back of the neck
Ever seen two furry animals, like dogs, in a fight? If you have then you might have noticed that when they are about to attack each other, the fur over their neck stands on its end and makes the animals appear bigger. The bigger the animals appear the more they are able to intimidate each other.

How our past experiences shape our behavior and personality

Our beliefs and needs are the strongest factors that govern our behavior. Ultimately, it all comes down to beliefs because a need is also a belief- a belief that we lack something.
