Consider the trajectory of Wes, a well-established professional photographer whose marriage to Rachel began facing strain after a decade together. While Wes had initially supported Rachel through her training to become a chef, the landscape of their lives shifted dramatically over time. The digital revolution hit Wes’s photography business hard, bringing professional doubt and personal vulnerability. Meanwhile, Rachel achieved a major career milestone by becoming the head chef at a respected local restaurant.

Thrilled yet overwhelmed by her new responsibilities, Rachel wrestled with intense fears that she would not measure up to the demands of her role. When she confided these anxieties to Wes, he attempted to offer encouragement by telling her to remain positive. Believing he was acting as a supportive partner, Wes failed to realize how his cheerful dismissals landed. Rachel experienced his remarks as condescending, prompting her to withdraw and keep her hurt feelings to herself. Both partners harbored hidden insecurities, yet an affair was the furthest thing from their minds.

This dynamic aligns closely with patterns studied extensively in relationship research, such as the framework described by Jinashree Rajendrakumar outlining how affairs develop over time. Relationships often begin to fray when everyday emotional bids—defined as gestures, questions, or expressions of vulnerability meant to elicit attention and support—are repeatedly met with turning away or turning against, rather than turning toward. When partners consistently miss these bids, trust erodes gradually, clearing the path for negative comparisons where one partner begins measuring the other unfavorably against someone new.

For Wes, the turning point arrived unexpectedly during a routine coffee shop visit. A red-haired woman accidentally dropped a wet umbrella on his foot while standing in line. She apologized, and as she left, offered a broad smile that caught Wes by surprise and genuinely lifted his mood.

The following day, their paths crossed again at neighboring tables. Her name was Tess, and she worked as a data analyst in the next town over. To Wes’s delight, they discovered a shared passion for silent films. Tess was single, friendly, and easy to talk to. At the time, Wes thought nothing could be more innocent than discussing classic cinema with someone sitting nearby. During their early interactions, he even made a point of mentioning his wife, Rachel, more than once, believing it established proper boundaries. Within six months, however, he would be keeping a far bigger secret from his wife.

What Is "Emotional Cheating"?

Defining emotional infidelity has become increasingly important for modern relationship counselors and researchers. The Cleveland Clinic defines an emotional affair as a type of connection that involves developing a deep emotional bond with someone other than a primary partner without fully disclosing the existence or depth of that connection.

Dr. Chivonna Childs, quoted by the Cleveland Clinic, notes that the boundary is crossed when interactions involve chemistry, physical attraction, or persistent thoughts and fantasies about the individual that do not stop. Once a relationship moves past that threshold, it leaves the realm of ordinary friendship and enters the territory of emotional infidelity.

To evaluate such interactions, relationship experts suggest asking critical self-reflection questions, such as considering how one would feel if a partner made the exact same decisions, or evaluating whether the external interactions ultimately support or harm the primary relationship.

While foundational researchers like John and Julie Gottman have traditionally focused on the broader mechanisms of building and losing trust over decades of study rather than treating emotional cheating as a distinct diagnostic category, their insights illuminate how emotional drift occurs. In the case study detailed in John Gottman’s book What Makes Love Last?—drawing from composites in the Gottman Institute’s research facility—Wes’s growing intimacy with Tess eventually culminated in a full physical affair. Yet long before that escalation, Wes was steadily cultivating a clandestine connection that he chose to hide from Rachel.

The Slippery Slope of Small Secrets

As weeks passed, the coffee shop table became a routine meeting place for Wes and Tess. Wes found himself shaving with extra care on days he hoped to cross paths with her, though he avoided examining his motivations even to himself. When Tess mentioned that online dating had proved unsuccessful for her, Wes replied, "I can’t believe someone as great as you can’t get a date," before instantly catching himself.

When a classic Chaplin film festival arrived at the local cinema, inviting Tess felt natural to Wes. Rachel was deeply busy at the restaurant and notoriously disliked silent films. Soon, Wes and Tess were attending movies together exclusively on nights when Rachel worked late shifts. Wes deliberately omitted mentioning Tess to Rachel, convincing himself that telling her would only cause unnecessary misunderstandings. He labeled it a harmless, small secret. Because Tess knew he was married, Wes reassured himself that he was doing nothing wrong.

According to relationship specialists Don and Carrie Cole, emotional infidelity in the Gottman Method typically begins the moment an individual allows themselves to get too close to someone outside the primary relationship, crossing invisible lines of intimacy.

Walls, Windows, and Misdirected Confidences

The dynamic in Wes’s marriage continued to deteriorate as he redirected his emotional life outward. Wes began confiding in Tess about marital frustrations and professional setbacks that Rachel knew nothing about. Specifically, Wes had pinned his hopes on securing a prestigious position at an advertising agency. When the job was ultimately offered to another candidate, Wes was devastated, and his uncharacteristic distress was immediately visible to Rachel.

"If you had told me about it," Rachel told him, "maybe I could have helped you prepare for the interviews. Even if you don’t think so, I know a thing or two myself."

Defensive and proud, Wes snapped back, "I don’t need your help."

The following day, Tess offered him a warm embrace and unreserved praise for his photography work. She made him feel valued, believed in, and understood—feelings he felt were entirely absent at home. In his altered perception, Tess now appeared prettier, sexier, and inherently kinder than his wife.

This behavioral shift reflects the principles outlined by Dr. Shirley Glass, a leading researcher on infidelity and author of Not “Just Friends.” Glass utilizes the metaphor of walls and windows to describe the architecture of a healthy marriage: a strong emotional wall protects the couple from outside intrusion, while transparent windows maintain open communication and connection between the partners.

In troubled relationships, as Jinashree Rajendrakumar notes, the internal window between partners is often replaced by a solid wall, while a wide window opens up to external figures. Secrets invariably begin with omission. By keeping Tess a secret from Rachel, and subsequently hiding his professional failures and interviews, Wes systematically dismantled the emotional barriers protecting his marriage.

What People Seek in an Affair

When relationships progress to physical affairs, outsiders often view the infidelity as the primary catalyst for a divorce or separation. However, Dr. John Gottman writes in The Seven Principles for Making Marriage Work that the reality is frequently inverted. In most cases, existing problems within the marriage create a trajectory toward separation, which in turn drives one or both partners to seek intimate connection elsewhere.

Furthermore, secret meetings and trysts outside a marriage are rarely driven purely by sexual desire. Instead, researchers find they are fundamentally about searching for friendship, support, understanding, respect, attention, and genuine care.

For a long time, nothing in Wes’s initial encounters with Tess resembled conventional cheating. The path began with missed emotional bids, cheerful dismissals of fear, and a gradual internal comparison that found Rachel lacking. Once Wes began concealing movie nights and professional setbacks, his behavior crossed firmly into the territory of emotional infidelity as defined by mental health professionals.

Experts emphasize that this outcome is rarely inevitable. Wes could have initially shared the coffee shop encounter with Rachel, using it as an opening to acknowledge that her demanding new career path had left him feeling vulnerable—an admission he avoided even to himself. By choosing silence, he inadvertently deprived his wife of the opportunity to offer love and support.

While missed bids, minor secrets, and fleeting frustrations can occur in any marriage without signifying infidelity, the true danger lies in accumulation. Over months, unaddressed resentments pile up until the person a spouse confides in most is no longer their life partner. By recognizing these early warning signs and patterns, couples can identify vulnerabilities and rebuild trust before minor disconnects escalate into irreversible damage.
