"Is He Really Cheating?" 9 Myths About Infidelity It's Time to Stop Believing

Infidelity is one of those topics everyone has an opinion about, yet almost no one has a universal answer. Some believe that “true love forgives everything,” while others are convinced that a single flirtation is enough to destroy a relationship. Social media, TV series, and advice from “experienced” friends only make the subject even more confusing.

Infidelity is one of those topics everyone has an opinion about, yet almost no one has a universal answer. Some believe that “true love forgives everything,” while others are convinced that a single flirtation is enough to destroy a relationship. Social media, TV series, and advice from “experienced” friends only make the subject even more confusing.

“Good women don’t get cheated on,” “If you keep an eye on your man, he’ll never cheat,” “If I forgive him once, he’ll never do it again”… Sound familiar? We hear these phrases so often that they begin to sound like unquestionable truths.

In reality, most popular beliefs about infidelity are myths that prevent us from seeing relationships clearly. Here are nine of the most common ones.

Myth #1. Cheating Is Only About Sex

For some people, cheating begins only with physical intimacy. For others, it starts with romantic messages, secret meetings, or an emotional attachment to someone else.

The truth is that there is no universal definition of infidelity. Every couple has its own boundaries and expectations. That’s why it’s important not to make assumptions, but to openly discuss what each of you considers cheating.

What one person calls “harmless flirting” can be a serious betrayal of trust for someone else.

Myth #2. If Someone Cheats, the Relationship Must Have Been Bad

It sounds logical, but reality is much more complicated.

Yes, sometimes infidelity is connected to a relationship crisis, lack of attention, or emotional distance. But there are also people who are happy in their relationships and still choose to cheat.

The reasons can vary widely:

• a need for validation;
• low self-esteem;
• a desire for novelty;
• revenge;
• learned relationship patterns;
• impulsive decisions.

Cheating does not always mean someone has stopped loving their partner.

Myth #3. A Relationship Can’t Survive Infidelity

Some couples break up immediately. Others go through a painful crisis and stay together.

Can trust be rebuilt? Yes—but only if both people are genuinely willing to work on it. A simple “I’m sorry” is not enough.

A relationship may survive one act of infidelity, but it’s much harder to survive repeated betrayals.

Myth #4. If I Control Everything, My Partner Won’t Cheat

Knowing phone passwords, checking messages, tracking locations, constantly asking “Where are you?”—these behaviors are often mistaken for care and concern.

In reality, total control doesn’t create trust. It creates tension.

Someone can be faithful without being monitored, and someone else can hide infidelity even under constant surveillance. Control doesn’t guarantee honesty—it only reflects a lack of trust in the relationship.

Myth #5. People Only Cheat With Someone Younger or More Attractive

This myth falls apart when you look at the stories of many beautiful, successful, and famous women who have been cheated on.

Infidelity is rarely about someone being “better.” Often, it has little or nothing to do with appearance.

If someone decides to cheat, their choice of another person is not necessarily determined by youth or beauty.

Myth #6. Women Cheat Much Less Often Than Men

The stereotype of “female loyalty” is far less clear-cut than many people think.

Research from different countries shows that both men and women can be unfaithful, although their motivations often differ.

For some women, cheating is an act of protest. For others, it’s a search for emotional closeness they feel is missing. For others, it’s simply an impulsive decision.

Gender alone does not determine a person’s likelihood of being unfaithful.

Myth #7. If Someone “Got It Out of Their System” Before Marriage, They Won’t Cheat Afterward

“He had his wild years, now he’ll be a devoted husband” is one of the most common hopes.

Sometimes that does happen. But past behavior is never an automatic guarantee of future behavior.

People change only when they genuinely want to—not because they got married.

Myth #8. Friendship Between a Man and a Woman Always Turns Romantic

Men and women can absolutely have genuine friendships without romantic intentions.

The problem isn’t friendship itself. The problem is secrecy, hidden communication, or breaking the agreements a couple has made.

Honesty matters far more than the gender of your friends.

Myth #9. It’s Easy to Tell When Someone Is Cheating

The internet is full of lists like “10 Signs Your Partner Is Cheating.” A new password, coming home late, wearing a different perfume, paying more attention to appearance…

The problem is that none of these signs, on their own, proves infidelity.

Suspicion can grow out of anxiety or a breakdown in trust. And people who truly want to hide an affair can sometimes do it remarkably well.

The only reliable way to understand what’s happening in a relationship is through an honest conversation—not by searching for “secret signs.”
