Most of the time, people don’t cheat intentionally. They don’t deliberately look for new sexual or romantic opportunities and betray their partner just because they can. They cheat because they meet someone they find interesting and/or attractive and lack the ability (willpower, commitment, gratitude, respect, and love) to end the connection and step away in time. Instead of realizing they’re being drawn in as more than friends, they naively continue to bond with the new person and feel validated by him or her.
By not taking any action, they get attached and create an inseparable emotional bond.
Some people also cheat without forming a connection, such as those who meet at clubs, bars, concerts, or special events. They cheat on impulse out of thrill or boredom without much or any thought or care for their partner. Such people justify their wrongdoing by blaming their partner or the relationship for their cheating. They make cheating okay in their heads by telling themselves their partner didn’t treat them well, give them enough attention, take them out, buy them things, sleep with them, or simply make the relationship challenging or interesting enough.
Due to unhealthy perceptions of their partner and unresolved relationship problems, they see opportunities to cheat as last-ditch efforts to be happy and sometimes even as ways to exit the relationship.
As you can see, people cheat for different reasons. Usually, they do it to fulfill their sexual urges, cravings, or fantasies. Other times (when a connection is built), they cheat with the intention to meet their emotional needs and feel desired, validated, or in control of their lives, especially those who felt controlled, oppressed, or abused throughout the relationship.
Cheating serves as an escape, which empowers and liberates victimized cheaters.
Some people also cheat out of revenge. They’ve been betrayed by their partner in the past, so they convince themselves they deserve that experience as well and that their partner did it first. Because of such thoughts, they lack loyalty and act on the chance to cheat as soon as an opportunity presents itself.
They operate on a tit for tat basis, so they justify their actions by mirroring what they believe their partner has done or might do. This mindset makes it easier for them to cross boundaries without much guilt, shame, or care.
It all comes down to their upbringing, values, and maturity. Those who observed commitment issues and instability in their childhood don’t necessarily cheat themselves, but they often inherit their parents’ traits, moral values, habits, conflict resolution skills, attitude, coping mechanisms, and so on.
Because their parents show them the ropes to life, they internalize many of those patterns—both healthy and unhealthy, and risk making similar mistakes in their relationships. It takes immense reflection and effort to be different and break unhealthy patterns inherited from parents.
Of course, parents aren’t solely responsible for how their children turn out. They don’t explicitly tell them to cheat or have unhealthy relationships. Instead, children often observe and absorb how their parents handle relationships and life in general. When they handle them a certain way, they set a standard, whether it’s good or bad. Ultimately, it’s up to each adult to figure things out and decide which patterns to follow and which ones to break.
They can’t blame their parents for their choices in life. Their parents may affect their thoughts, feelings, and even responses, but it’s their job to realize this and change them if necessary.
Cheating is a serious offense. Whether a relationship is healthy or struggling, it shows how prepared couples are to deal with stress, fears, doubts, temptations, and other unwanted/inherited feelings and issues. If they’re immature and reactive, they often take the relationship for granted and cheat, expecting their cheating partner to give them or make them feel something their partner couldn’t.
Some can’t commit or think they can find a better partner. So as soon as “someone better” shows up, they get hopeful about that person’s good traits and forget everything their partner did for them and the relationship. Instead of being grateful and bonding with their partner, they focus on their partner’s bad moments and traits and convince themselves they deserve happiness, even if it’s with someone else.
This opportunistic mindset forces them to “follow their heart,” aka emotions, and ruin the relationship from within. Even if the relationship doesn’t break, it develops trust and/or commitment issues that require immense effort to overcome.
So if you want to know why people cheat in relationships, especially in decent relationships, they do it because they’re unhappy or think they’re unhappy and deserve everything life has to offer. They don’t have the strength and willpower to say no to people who find them (sexually) attractive, so they entertain them and get hooked on them. Eventually, they get too close and comfortable and cross all friendship boundaries.
When that happens, they say YOLO and do what their heart most desires.
You probably remember how obsessed you were and how badly you wanted to be with your partner when you were in the early stages of getting to know each other. You remember thinking about this person all the time, even when you were busy.
That’s how people who develop a tight bond feel. They want to spend all their free time with the person they’re infatuated with, so they get even closer emotionally. Because they don’t understand or care what’s happening to them emotionally, they don’t hold back and let their happy hormones naturally cross all boundaries.
When it comes to cheaters, hormones bring them sexually close. First, they emotionally cheat, and then (when a connection is built), sexually as well. That marks the beginning of true self-awareness and perhaps even guilt or shame.
In today’s post, we’ll discuss why people cheat on their partners and share some valuable tips with you.
Why do people cheat?
People have an uncanny ability to take anything for granted, including those who love them and do everything for them. They stop valuing those who give them things for free on a daily basis and look for additional benefits from those who pique their interest and tempt them.
New people are always more attractive than long-term partners. They’re unpredictable, exciting, and come with a sense of novelty. Unlike long-term partners whose patterns and behaviors are familiar, new people offer mystery and the illusion of endless possibilities. This contrast makes them seem more appealing in the short term, as they seem to be flawless. In truth, their flaws are merely hidden. They have problems of their own that tend to reveal themselves months later.
Cheaters don’t think that far ahead. They think about the present moment and try to get what they crave or need right away. Because they think with their emotions, they ignore their values, commitments, and promises—and act on impulse. Impulse-driven behavior is common for those who lie, steal, or cheat.
Oftentimes, they convince themselves they’re the victims and that their relationship was dead anyway. In their mind, they believe they had to cheat and leave to save themselves from someone who couldn’t give them what they deserved.
You need to understand that cheating happens when people neglect themselves and their relationships. When they entertain relationship-destructive thoughts and refuse or fail to bond with their partner, they make room for other people in their lives. For people who will make them feel understood, cared for, attractive, and desired.
Their lack of happiness with themselves and/or their relationship causes them to prioritize other people over bonding with their partner. When they let someone else take their partner’s place and lean on him or her for various emotional needs, it’s only a matter of time before they get attached and stop seeing their partner as their life partner. They soon become doubtful and find their partner difficult, annoying, or unfulfilling.
This causes a complete emotional disconnection and urges them to connect with the new person.
Although every person has different relationship challenges and ways of dealing with those challenges, they cheat for similar emotional reasons. They want to feel fulfilled in ways their partner couldn’t or wouldn’t fulfill them. Because they take their partner for granted and want more than their partner can give, they let someone they know very little about close to them.
That person makes them feel how they felt when they were falling in love with their partner, so they think poorly of their partner. They don’t understand that they’re emotionally cheating and that they’ll eventually sexually cheat as well.
By the time they start flirting and realize things may have gotten out of hand, it’s already too late because they’re incredibly obsessed with obtaining validation from the new person.
So if you want to know why people cheat in (healthy, long-term) relationships, most of them cheat because they want a more meaningful or powerful romantic or sexual experience. They want a relationship or one-time thing to satisfy their urges and take their life in a new or more meaningful direction.
I don’t know how cheating could possibly do that, but they hope that their cheating partner will give them the answers they seek and solve their problems. Some cheaters cheat once or multiple times before realizing their new partner isn’t any better than their previous partner. Others continue to cheat until they decide to abandon their relationship and monkey-branch to the new person.
Usually, they leave their partner for a new person when they know the new person loves them and wants to be with them long-term. That gives them the certainty to jump ships and enjoy their life to the fullest.
Monkey-branching is a cowardly way of ending a relationship and immediately starting a new one. But that’s why the new relationship is often built on lies and deceit. It struggles with trust and commitment, something new relationships usually don’t have to worry about.
Some call it karma for cheating and thinking the new relationship would be perfect.
All in all, people cheat to boost their ego and validation. Cheating allows them to feel empowered and temporarily ignore their problems and challenges. Sooner or later, though, they’re forced to deal with their old problems, plus the ones that cheating has caused.
Most people encounter a few opportunities to cheat throughout their lives. Whether they act on them depends on their values, self-control, and the state of their current relationship. If they have decent values, self-control, self-love, and love for their partner, they easily pass the test of strength, commitment, and loyalty, as they see their partner’s value and fear losing him or her.
As for those who consider their relationship unfulfilling and see nothing wrong with doing what’s best for them, they allow themselves to connect with others and act on new romantic or sexual urges and opportunities. They’re ready to discard their partner the moment they find someone who offers different or better security, benefits, or experiences.
Having said that, here’s why people cheat on their partners.
You can’t prevent your partner from cheating
Other than being a good (not perfect) partner, you can’t prevent the person you love from cheating on you. If your partner focuses on the bad aspects of the relationship and ignores the good, while forming a new emotional bond with someone else, nothing you say or do can prevent them from feeling understood, validated, and connected.
You’d have to catch them early on for them to feel guilty and part ways. And even if that happened, it wouldn’t necessarily stop them from falling in love and guarantee happiness in the relationship.
Cheaters have to learn a powerful lesson. They must get caught cheating or fail at starting a successful relationship once they’ve cheated. When that happens, they can finally be forced to think about their choices and decide if they’ve made a mistake.
Before they reflect and realize their wrongdoings, they must feel hurt and want things to change.
So bear in mind that you can’t avoid cheating just by being on your best behavior and wanting your partner not to cheat. Some people cheat because they see their partner’s niceness as a weakness. They don’t take him or her seriously because they get everything their heart desires on a silver platter.
Such people have a lot of growing up to do, as they don’t value relationships in which their partner is very giving and willing to sacrifice his or her own happiness for theirs.
If you want to do your best to prevent your partner from cheating, find someone with good values. Pick a person who values long-term commitment, resists temptations, and likes you for who you are, not how you look or what materialistic things you can provide.
Secondly, maintain your bond. Do that by spending quality time together, expressing gratitude, and resolving differences and difficulties compassionately and maturely. You or your partner will have a much smaller chance of developing feelings or acting on temptations toward someone else if you remind each other why you’re together and stay connected.
And thirdly, have a purpose outside of the relationship. Couples often lose feelings and hope when someone invests significantly more into the relationship than the other. That causes a big imbalance in terms of interest and power, making the attached and committed person even less attached and committed.
A healthy relationship requires healthy investment from both parties. Make sure things are even (or as even as they can be), so neither of you looks for a “higher-value” individual elsewhere.
