What Does Cheating Say About A Person?

Updated on October 22, 2025

You’ve probably heard the saying, “Once a cheater, always a cheater.” You might have read it online or heard it from someone that people who cheat often do it again and continue to damage or destroy their relationships.

But is it true? Do people really make the same mistakes over and over again in relationships and fail to break their cheating patterns?

The answer depends on each person’s regret, guilt, and ability to learn from mistakes. But in general, people don’t change unless they have a strong desire to change. Unless they suffer from their misdeeds and badly want to improve their behavior, they tend to follow their instincts and make similar mistakes throughout their lives.

They lie, express anger poorly, or cheat, and by doing so, fully transform themselves into serial offenders or cheaters.

Sometimes, they even project their problems onto their partner and blame their partner for their cheating.

They tell their partner things like:                                                    

• you made me do it
• it’s all your fault
• if you weren’t like this…
• I wasn’t happy
• we were on a break
• you would have done the same
• you cheated first

When a person cheats, the indisputable truth is that no other person is responsible for his or her cheating. It doesn’t matter if the relationship wasn’t working or an ex from 20 years ago showed reappeared. The cheater is solely to blame for cheating, as he or she gave in to temptations and decided to betray his or her partner.

The cheater may put the blame on alcohol or drugs, pushy friends, or even the person he or she shamelessly cheated on, but that doesn’t change the fact that he or she made a conscious decision to sleep with another person. The cheater was okay with the consequences of unfaithfulness. And that says a lot about his or her morals, integrity, self-control, and care for the relationship and the future.

Someone who cheats simply isn’t ready for a relationship. He or she may become ready later, but during or shortly after cheating, the cheater is completely unprepared to handle temptations and maintain relationships. I suppose the cheater is too impulse-driven to learn important lessons and prioritize what or who truly matters long-term.

If he or she wasn’t happy or mature enough for a serious commitment, he or she should have left the relationship instead of acting on temptations and cheating. He or she should have stepped away before the relationship evolved and emotions developed. Had the man or woman done that, there would have been no need to cheat and perhaps even monkey-branch into a new relationship and ruin his or her karma.

That would have been the ideal/moral thing to do. In the real world, though, things don’t always unfold like that. Many people are happy or happy enough with their partner, but still cheat. They do so because they neglect the connection with their partner and allow themselves to get close to another person.

Due to the excitement of getting to know someone else, the new person validates them more than their partner and urges them to do what feels right rather than is right. And what feels right is the worst for the relationship, as it often ruins trust and breaks the relationship completely.

A relationship struggles to recover from infidelity once trust is broken and anxiety takes over.

In this article, we’ll talk about cheating and answer the question, “What does cheating say about a person?”

1)Impulsive

Cheating says many (mostly bad) things about a person, but the worst is that it shows how careless and emotion-driven he or she can be.

It shows that the cheater is ruled by emotions and lacks the willpower to say “no” to new romantic or sexual opportunities. If the cheater had decent emotional self-control and loyalty to his or her partner, he or she would have pulled away in time and stopped cheating from happening.

That’s why it’s safe to say that cheating says that the cheater’s priorities and morality are under par and that he or she doesn’t value what he or she has or had.

A person who cheats prioritizes his or her emotional and sexual gratifications over his or her partner’s commitment and well-being—and ignores the need to work on the relationship.

So if your boyfriend or girlfriend cheated on you and you’re wondering what cheating says about a person, know that it doesn’t say anything good. It’s a clear sign that the cheater lacks self-control and the positive, reinforcing thoughts that could have saved the relationship.

The cheater’s mindset revolves entirely around his or her fulfilment, which is not enough to stay faithful to you or to the relationship. As long as he or she thinks the world revolves around him or her, the cheater will continue to prioritize his or her own desires over your feelings and the health of the relationship.

Impulsive people are known for making illogical decisions. They make such decisions even though they hurt them and the people around them. Pain doesn’t stop them from putting themselves first and living their life in the moment.

2)No self-respect

Although a cheater is emotionally-driven, he or she always makes a premeditated decision to cheat. This means that the cheater decides it’s okay to cheat and that he or she wants to do it because it’s good for his or her validation and sexual fulfillment.

There truly is no excuse for cheating, which is why you shouldn’t instantly forgive a person who betrays you. It doesn’t matter if it’s a physical or emotional betrayal. Cheating is still cheating and must be taken seriously regardless of how it happened and with whom.

You have to remember that cheating occurs when people stop caring about their partner and themselves (their values). They do whatever feels right to them—and as a result, hurt the person who loves them the most.

This implies that they don’t care about how others perceive them or how they perceive themselves. They stopped caring about such things the moment they developed feelings or sexual cravings for someone else.

So if you’ve been cheated on or know someone who’s been betrayed, remember that cheating says bad things about the person who cheated. It shows that the cheater doesn’t hesitate to betray others for selfish gain and that he or she doesn’t care about personal values and people’s emotions and feelings.

This takes us to our next point.

3)Inconsiderate

It’s no secret that a person who cheats is incredibly self-centered.

He or she doesn’t think about how cheating will affect his or her loyal partner’s feelings and how many trust issues and problems it will cause.

A cheater is just too self-absorbed and inconsiderate of others’ feelings to do the right thing (which is to recognize his or her impulsive desire to be intimate with another person).

In all honesty, cheaters often see themselves as victims. They believe they were wronged and robbed of happiness and opportunities and that they need to do what’s best for them.

That’s why they attempt to justify their betrayal and sometimes even make themselves look better than they actually are by making their partner look bad.

They do this by trash-talking their ex-partner, revealing their ex’s secrets, and ruining their ex’s reputation. It’s unfortunate that such cheaters exist and that cheating has become such a common phenomenon.

If people saw cheaters’ true colors before they got attracted and attached to them, they wouldn’t have committed to them. They would have avoided getting involved with them in the first place or soon run for the hills.

But since cheaters hide their cheating tendencies, or don’t even realize they have them, their partners usually discover them when it’s already too late.

Cheatees (those who get cheated on) get to know their partners’ bad traits and see them for who they are. It’s unfortunate that they have to suffer so much due to the inconsiderate actions of their immoral partners.

With that said, here’s why people cheat in relationships.

4)Thirst for validation

There are many reasons why a cheater cheats. But one of the most common reasons has something to do with how a person thinks of himself or herself.

Basically, the worse a person views himself or herself and the more he or she craves validation externally, the higher the chance that he or she will cheat when an opportunity arises.

Low self-esteem alone isn’t enough to make a person cheat. Many people with low self-esteem cling to their partner and commit to him or her more than people with decent self-esteem. It’s those who crave others’ recognition and can’t get enough of it that take their partner for granted and cheat on him or her.

Such people are so hungry for attention they’re willing to throw their relationship away for a bit of external validation and entertainment. They don’t understand that long-lasting relationships require them to consistently work on themselves and the relationship.

5)Lack of emotional strength

Everything in life requires strength—and relationships are certainly no exception.

Relationships require positive thinking, self-control (especially during arguments), lots of healthy communication, healthy thinking and perceptions, and much, much more.

So when someone thinks that “A relationship shouldn’t be this hard,” remember that he or she is at risk of adopting the belief that he or she could be happier alone or with someone else. In his or her mind, looking for greener pastures elsewhere may seem like a better idea.

A person with such thoughts is basically on the verge of losing his or her emotional control and doing something that will brand him or her as a quitter or even worse, a cheater.

It’s only a matter of time before he or she finds an opportunity to leave the relationship. The only question is how he or she will leave. Will it be because of an argument or perhaps a new romantic or sexual interest?

Due to his or her poor commitment, this person will eventually:

1. Reach the tipping point and break up with his or her partner.
2. Cheat on his or her partner and consider starting a new relationship from scratch.

Whatever a cheater decides to do, he does it because he believes it’s the right thing to do. He just needs to make certain that the person he likes also likes him back.

Remember, when it comes to cheating, there are no mistakes. There are only people who never learned to value others or understand the importance of loyalty and dealing with temptations.

6)Untrustworthy

One of the most common mistakes we make is to trust people who tell us what we want to hear, not need to hear. We trust smooth-talking people because, from a young age, we’ve been taught to be honest and respectful and to expect the same in return.

But unfortunately, we don’t always get back what we give. Sometimes it’s because of our own actions, but more often, it has nothing to do with us at all. How people treat us is a reflection of their maturity, personality, and love (or understanding of love).

Cheaters and liars are good at saying the right things. They don’t think about the future, so they say and do things that feel good in the moment.

They got away with lying and cheating in the past, so they learned that lies are a normal way of life. As a result, they turned into people who stopped caring about their morals and refused to change their unhealthy behavior.

So keep in mind that it’s not unusual for cheaters to promise us the world and make us believe anything they want us to believe, starting with how much they love us and how committed they are. They want us to think they can be trusted and that they value the relationship and our needs.

But when it comes to actually fulfilling their promises, they fall short, as they fail to match their words with their actions. Giving up sounds better to them than taking responsibility and investing time and effort into the relationship that has encountered difficulties and requires effort to evolve.

And that’s what makes cheaters and liars so untrustworthy. Their unpredictable nature creates too much uncertainty for anyone to feel safe with them.

7)Unhappiness in a relationship

People who cheat aren’t emotionally or sexually content in a relationship with their partner.

They feel that they deserve more or better than what their partner can give them, so they consciously or subconsciously keep an eye out for new romantic or sexual opportunities.

When that opportunity finally arises, they seize it and do what feels right in the moment (cheat).

Like everyone else, cheaters believe they have the right to be happy, even if it means going behind their loyal partner’s back and betraying him or her in the worst way imaginable.

Many cheaters justify their immoral actions and pretend that they didn’t have a choice but to cheat. They convince themselves (and sometimes even others) that they were in a tight spot and that they had to find themselves and learn new things. Such beliefs assuage their guilt and make it easier for them to let go of the past.

I know that breaking up with someone who loves you can be difficult, but cheating is inexcusable. It shows that your partner or ex-partner is a low-integrity coward who puts himself or herself first, even if it hurts you immensely.

8)Lack of gratitude

If you’re still wondering what cheating says about a person, it says that the cheater doesn’t value his or her loyal partner’s effort and commitment.

It shows that he or she isn’t grateful for all the good memories and everything his or her partner did throughout the relationship. Cheating basically reveals what a person thinks and how he or she feels about you.

So always judge a person by his actions, not his words. Positive words are nice, but actions reveal how a person handles challenges, fears, pain, and temptations. If your (ex)partner cheated on you, you need to understand that you fell in love with an infatuated image of the person you wanted your partner to be.

You liked how your partner presented him/herself and adored the love that he or she gave you. It seemed and felt right to pursue the relationship at the time. But when your partner grew close to someone else and cheated on you, the ideal image you had of your partner shattered and revealed his or her true colors.

That was when your partner finally non-verbally told you, “This is who I am at my worst. My actions show how I feel about you and how I treat people I don’t value.”

I don’t remember who wrote it, but he said that we make reliable friends under difficult circumstances – when we or they need help the most. Difficult conditions tend to shape us into better people or conversely, bring out the worst in us.

And the same goes for cheaters. We meet our partners’ worst characteristics when they cheat, no longer needs us, or leave us for someone else.

It sucks, but that’s when people have nothing to lose and stop caring and pretending to be someone they’re not.

So try not to blame yourself for another person’s infidelity because it’s got very little or nothing to do with you. It’s got everything to do with the cheater’s problems that you couldn’t detect or do anything about.

My advice is to focus on yourself so that you can continue to grow and develop yourself into the person you want to be. The cheater will have to learn his or her lessons the hard way – by failing in relationship. When he or she fails, you likely won’t care because you’ll be over him or her and have better people to think about.
