Yes, insecurity, particularly low self-esteem and a need for external validation, is a very common underlying factor in infidelity, though people also cheat for excitement, relationship dissatisfaction, or personal issues like trauma. Cheaters often seek reassurance of their desirability or dominance, using affairs to boost self-worth, even if it ultimately harms themselves and their partner, according to Health, Psychology Today, Psychology Today, and YourTango.
For some individuals, low self-esteem and insecurity may be the driving force to cheat, to seek external validation or feel desirable. Paradoxically, in trying to boost their self-worth through infidelity, they ultimately harm others—and often themselves.
A cheating man's mindset often involves a mix of selfishness, insecurity, and entitlement, driven by a desire for validation, excitement, or escape from relationship issues, leading to rationalizations like blaming his partner or minimizing the affair's impact, while lacking empathy or remorse for the betrayal. They might feel inadequate and seek external affirmation, crave power, or struggle with commitment, sometimes seeing the affair as a solution rather than acknowledging deeper relationship problems, say experts.
Nine Common Signs Your Partner Is Cheating
The 80/20 rule in relationships explains cheating as the temptation to abandon a solid partner (80% good) for someone new who seems to offer the missing 20% of needs, a pursuit often leading to regret as the new person lacks the original 80%. Infidelity often arises from focusing on flaws (the 20%) rather than appreciating the substantial good (the 80%), making an affair partner seem appealing for fulfilling that small gap, but ultimately resulting in losing the valuable foundation of the primary relationship.
Although not everyone experiences each stage and they can occur in any order, these stages are:
One thing that cheaters often do is say one thing and do another. For example, it is so easy for someone to tell you they love you, but when you never see them perform any actions that indicate that they love you like: doing something thoughtful like buying you flowers, well, then this could be a red flag.
The 3 Stages of an Affair
Carder says many studies suggest an emotional affair is just as painful for wives. In fact, he says emotional affairs become more painful as the infidelity moves through its multiple stages. The first stage is the mood-altering effect when a man sees the other woman or a message from her.
There isn't one single "best" predictor of cheating; rather, it's a combination of factors, with relationship dissatisfaction, low sexual satisfaction, mismatched sexual desire, and poor communication being the strongest predictors, often alongside individual traits like insecure attachment styles, impulsivity, and a history of infidelity. Ultimately, a lack of emotional connection and unresolved relationship issues significantly increase the risk, according to this Psychology Today article, this National Institutes of Health article, and this Medium article.
In surveys of individuals who have cheated, falling out of love, seeking variety, and feeling neglected were the most commonly cited reasons, followed by situational forces, a desire to raise self-esteem, and anger with a partner.
Cheating body language cue #1 – No eye contact
Too little eye contact in a conversation can be a hint your partner is having an affair. A cheater will always look away when they're asked a direct question. This is especially true when quizzed about their whereabouts.
Studies show that less than 2% of relationships starting in affairs last more than 2 years, and the majority of those know by 6 months that they are not happy in the relationship, but feel as though they have to make it work because they blew up their life to be with that person.
There are several types of personalities that have been found to be more prone to cheating, including narcissists, psychopaths, and those with an avoidant attachment style.
Common signs that may indicate insecurity in a relationship include excessive jealousy, low self-esteem, overprotectiveness, a fear of criticism, and a constant need for reassurance.
The workplace is where most affairs begin. It doesn't hurt that we usually dress nicely and are on “good behavior” at work. Plus, having shared passions about projects (or mutual annoyance at a boss or co-worker) provides the perfect breeding ground for an affair.
Interestingly enough, some individuals who cheat also exhibit signs of dissatisfaction long before they actually stray. They may withdraw emotionally from their partners or display irritability over minor issues—a signal that something deeper is amiss within themselves rather than solely within the relationship.
But it does provide some rough guidelines as to how soon may be too soon to make long-term commitments and how long may be too long to stick with a relationship. Each of the three numbers—three, six, and nine—stands for the month that a different common stage of a relationship tends to end.
Soft cheating (or micro-cheating) involves subtle, often digital, behaviors that cross relationship boundaries and breach trust without being full-blown infidelity, like excessive social media interaction with others, hiding messages, or maintaining secretive contact with an ex, often stemming from a need for validation but eroding intimacy and causing insecurity.
Changes in Physical and Personal Appearance
One of the most noticeable warning signs of a cheating partner is a sudden shift in their physical and personal appearance.
Previous litera- ture has identified characteristics of the partner involved in infidelity; this study investigates the Big Five personal- ity traits (openness, conscientiousness, extraversion, agreeableness, and neuroticism) of uninvolved partners.
Most cheaters stay with their partner because they never really did want to end the relationship, even if it was disconnected or emotionally up and down. After an affair has ended many cheaters are surprised by how much love they feel for their partner.
Betrayal trauma activates the brain's threat detection system in profoundly destabilizing ways. According to neuroscientific research, the brain responds to betrayal in a manner similar to how it responds to physical danger because, on a relational level, it poses a threat to survival.

How Do Most Emotional Affairs End? Emotional affairs tend to end in one of two ways. You and your spouse can address the emotional disconnection in the marriage and work to revitalize your relationship, or you can decide to part ways with one another through divorce.
