Why People Cheat Even in Happy Relationships Shares Expert?

Quick Summary

• Infidelity can occur even in relationships that appear happy and stable.
• Emotional neglect, low self-esteem, the desire for excitement, and unresolved trauma are common contributing factors.
• Recognising these underlying issues early can help couples strengthen communication and rebuild trust.

We all know that no relationship is perfect. Even when a couple appears to be happy and content in their relationship, what we see is often only the surface. Behind every smile, there may be disagreements, disappointments, insecurities, or silent struggles that remain hidden from everyone else.

We often assume that people cheat because they are unhappy. But that isn’t always true. Infidelity can happen even in seemingly happy relationships. Sounds strange? If you are wondering what could be the reasons for that, then let’s find out from eminent marriage counsellor and infidelity therapist in Delhi, Shivani Misri Sadhoo, why people cheat even in happy relationships.

What Do You Mean By Cheating/Infidelity In A Relationship?

When you suddenly start sharing your emotions, affection, or physical connection with someone outside your relationship while keeping it a secret from your partner, it is called cheating. In simple words, cheating implies a breach of trust.

Cheating and Infidelity are often used interchangeably. However, they are not always the same. Cheating is a broader term that includes any secret behaviour that breaks your partner’s trust, whether emotional, physical, or even online. To put it simply, every act of infidelity is cheating, but not every form of cheating involves physical intimacy.

“Cheating is rarely about the happiness of a relationship alone—it often reflects unresolved emotional needs, personal insecurities, or unhealed wounds. Understanding the ‘why’ is the first step toward building healthier, more trusting relationships.”  Shivani Misri Sadhoo, Gottman Recommended Indian Marriage Counsellor | Clinical Psychologist at IBS Hospital, Lajpat Nagar, Delhi

1. Feeling Neglected

Sometimes, even if the couple is in a happy relationship, a person can quietly begin to feel invisible. We are living in an era where time is precious. Life is hectic. Everybody is busy. So, the little gestures that once made them feel cherished may slowly fade. They may not feel unhappy with their partner, but they somehow feel neglected, as if their feelings no longer hold any meaning for their partner.

They simply feel invisible and ignored. If someone else offers the attention, affection and appreciation that were missing in the relationship, then they feel tempted and cheat on their partner. The affair is not always about finding someone better, but about feeling better about oneself.

2. For A Thrilling Experience

When couples are in a relationship for a very long time, it sometimes becomes boring. The same old routine, the same conversations, and the same responsibilities can make the relationship seem less exciting than it once was. So, this is when some people want to add a spark to their otherwise monotonous life.

And, they feel that a new person would be able to bring that fun into their life. The secrecy, attention, and excitement of something new can feel addictive for a while. But that excitement is usually transient, often leaving behind broken trust, guilt, and lasting emotional trauma.

3. Low Self-Esteem

Sometimes people with low self-esteem struggle to believe they are truly enough, no matter how much their partner loves them. The admiration of someone new can feel like proof of their worth, offering a fleeting sense of validation that temporarily quietens their inner doubts. It is rarely about loving their partner less; it is about constantly needing reassurance from outside. Unfortunately, even a happy relationship cannot fill a void that exists within. This makes infidelity an unhealthy attempt to soothe deep-seated insecurity.

4. Unhealed Emotional Scars

Sometimes, the roots of infidelity lie far deeper than the relationship itself. Unresolved childhood wounds, past trauma, or an avoidant attachment style can quietly shape how a person responds to love. The closer and safer a relationship becomes, the more exposed they begin to feel.

Instead of embracing that proximity, they may instinctively push it away. For instance, think of someone who is happily married but is still emotionally involved with, perhaps, an office colleague or someone introduced through a mutual friend. It is not always a search for a better partner but an unconscious attempt to escape the vulnerability that genuine intimacy demands.

These are only a few of the many reasons why people may cheat, even when they are in a seemingly happy relationship. Infidelity is rarely caused by a single factor. More often, it is a mix of unmet emotional needs, personal struggles, and unresolved issues. Understanding the reasons behind it does not justify cheating, but it can help couples recognise problems early and work towards rebuilding trust and strengthening their relationship.
