About 20% of married men report cheating, compared to 13% of women, though figures vary by study and broader definitions of infidelity (emotional/physical) push estimates higher, sometimes to 60% for men, with younger couples showing closer rates and older men cheating more often, according to Institute for Family Studies data.
Studies show that men tend to cheat more often than women in marriages. About 20% of married men cheat, compared to 13% of married women. This gender gap in infidelity has been consistent across various research findings. Men are more likely to engage in sexual infidelity and to do so multiple times.
Extramarital Affairs/Infidelities are common. Most estimates indicate that around 60% of men and 45% of women are willing to report that an affair has occurred sometime in their marriage and it suggests that 70% of all marriages experience an affair.
Research points to men. Surveys (like those from the Institute for Family Studies) show about 1 in 5 men admit to cheating, compared to about 1 in 8 women.
According to the Institute for Family Studies, about 20% of married men admit to cheating. But when you include relationships outside marriage and account for underreporting? That number rises to nearly 1 in 3. (Source: ifstudies.org, brides.com)
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.
But during this period, older men have the same tendency to cheat as their younger peers. The survey says that infidelity among men peaked at the age of 50 to 59 (31%). The number decreases as the men age during this period. For women, the highest infidelity rate is from ages 40 to 49 (18%), which declines as they age.
Yes, a man can cheat and still love his wife, as infidelity can occur for many reasons that are not always rooted in a lack of love for his wife. Because what men regard to be love is care, support, attention, and communication.
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.
Men still cheat more than women overall, but the gender gap is narrowing among younger generations. Infidelity rates peak at different age ranges for men (60-69) and women (50-59), showing age-specific patterns. Both psychological factors and relationship dynamics influence cheating behavior across all demographics.
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.
After cheating, a guy might act distant and secretive (hiding his phone, staying out late) or overly attentive out of guilt, often becoming defensive, irritable, or starting arguments. He might change his routine, appearance, or habits, developing new interests or sudden hygiene changes, and often shows emotional withdrawal, resentment, or stonewalling when confronted, with signs varying based on his personality and feelings about the affair.
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.
It turns out, the chance of infidelity increases as much as 25 percent over the course of a relationship. And up to 60 percent of people will cheat at some point during their marriage. Yikes.
People who had stronger sexual interests, more permissive sexual values, lower subjective satisfaction with their partner, weaker network ties to their partner, and greater sexual opportunities were more likely to be unfaithful. Rates of infidelity among women are thought to increase with age.
There are several countries in which cheating is relatively common. Thailand is an outlier, but it is also at the top of the list. More than half of people in Thailand who are married admit to committing infidelity at least once during the course of the marriage.
The 7-7-7 rule is a structured method for couples to regularly reconnect, involving a date night every 7 days, a weekend getaway every 7 weeks, and a kid-free vacation every 7 months.
In most cases, affairs end peacefully and in secret. By their very nature, there is not much of a commitment to hold them together, and a desire to do the "right thing" is usually the excuse an unfaithful spouse uses to end it. But the real reason is usually that the affair has become more trouble than it's worth.
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.
According to studies, men are most likely to cheat after 11 years of marriage, while women get the itch between seven and 10 years of wedded bliss. One of the more interesting infidelity statistics is that married women are most likely to cheat around the age of 45, and men peak in cheating around age 55.
The 2-2-2 relationship rule is a guideline for couples to keep their bond strong and fresh by scheduling regular, dedicated time together: a date night every two weeks, a weekend getaway every two months, and a week-long vacation every two years, which helps prioritize connection, break routine, and create lasting memories. It's a framework to ensure consistent quality time, even with busy schedules, to prevent boredom and strengthen partnership.
Yet, most affairs usually end one of two ways: with divorce or a stronger current relationship. How the end plays out is up to you, how you choose to react, and how hard you want to work to stay together. Learning how to overcome grief and pain is going to be difficult, but Couples Academy can help.
Sometimes, marriages leave certain emotional needs unfulfilled, creating conditions that may lead to an affair. These unmet needs often include the longing for affirmation, admiration, and appreciation. Many men have a longing to feel valued and respected for their efforts.
Interestingly, the most common time for infidelity to occur is after approximately seven years of marriage, on average. However, there is a gender difference in the infidelity patterns over time.
There's no single way that affairs come to light, but the most common way is through accidental discovery. Maybe a partner stumbles upon suspicious text messages, sees an unexplained charge on a credit card, or notices a sudden behavior change.
