Consider the trajectory of Wes and Rachel, a composite couple studied extensively in the Love Lab by renowned relationship researchers Dr. John and Dr. Julie Gottman, and detailed in Dr. John Gottman’s book What Makes Love Last?. When Wes married Rachel, he was an established photographer who proudly supported her through culinary school. Ten years later, however, the digital revolution had profoundly disrupted his photography business. At the exact same time, Rachel achieved a major professional milestone, becoming the head chef at a highly respected restaurant.

While Rachel was thrilled with her new leadership role, she was also plagued by imposter syndrome and fear that she would not measure up to the demands of the kitchen. Whenever she confided these anxieties to Wes, he attempted to cheer her up by telling her to remain positive. Wes genuinely believed he was offering encouragement and playing the role of a supportive spouse. Rachel, however, experienced his cheerful dismissal as condescension. Feeling unheard, she stopped sharing her professional vulnerabilities altogether. Wes, meanwhile, was wrestling with his own deeply buried career doubts. If an outside observer had asked them at that precise moment whether their marriage was in jeopardy, both Wes and Rachel would have confidently ruled out the possibility of an affair.

The Slippery Slope of Emotional Intimacy

The dynamic shifted completely on an ordinary afternoon when a red-haired woman accidentally dropped her wet umbrella on Wes’s foot while standing in line at a local coffee shop. The woman, who introduced herself as Tess during a chance encounter at neighboring tables the following day, shared Wes’s rare passion for silent films. Single and working as a data analyst in a neighboring town, Tess was easy to talk to. Wes initially viewed their conversation as entirely innocent—after all, what could possibly be harmful about discussing classic cinema with a stranger at an adjacent table?

Yet, as the weeks progressed, small choices began to accumulate. Wes found himself shaving with extra care on days he hoped to cross paths with Tess at their routine coffee shop table. When Tess mentioned that online dating had proven unsuccessful for her, Wes replied, "I can’t believe someone as great as you can’t get a date," before abruptly catching himself.

When a Charlie Chaplin film festival came to the local cinema, inviting Tess felt natural to Wes, particularly because Rachel was perpetually busy at the restaurant and openly disliked silent films. Wes began arranging their outings exclusively on nights when Rachel was working late shifts. He deliberately omitted mentioning Tess to Rachel, convincing himself that his wife might misunderstand a harmless movie outing with a friend. He categorized his silence as a harmless, minor secret, reassuring himself that he was doing nothing wrong because Tess was fully aware that he was married.

According to relationship experts Don and Carrie Cole, writing for the Gottman Institute on the origins of emotional infidelity, emotional affairs typically begin when an individual allows themselves to get too close to someone outside of their primary romantic partnership.

Defining Emotional Cheating

The Cleveland Clinic officially defines "emotional cheating" as a type of emotional affair that involves developing a close, intimate emotional connection with someone other than a partner without fully disclosing the existence of that connection. Dr. Chivonna Childs, a psychologist cited by the clinic, explains that the boundary separating a platonic friendship from emotional cheating is crossed the moment chemistry, physical attraction, or persistent, lingering thoughts and fantasies about the other person enter the picture.

The Cleveland Clinic suggests that individuals evaluate their own behaviors by asking two pivotal questions: How would you feel if your partner made those exact same decisions, and do these ongoing interactions ultimately support or harm your primary relationship?

In the case of Wes and Rachel, the emotional architecture of the marriage was steadily eroding through what relationship researchers describe as the Gottman-Rusbult-Glass Cascade. Outlined by researcher Jinashree Rajendrakumar, this conceptual framework details how trust gradually deteriorates over time. The cascade frequently originates when routine bids for emotional connection—defined as gestures, questions, or expressions of vulnerability meant to elicit attention or support—are consistently met with turning away or turning against, rather than turning toward.

Every time Rachel confided her fears about her chef position and Wes responded with generic, cheerful advice, he was effectively turning away from her emotional bid. Over months and years, these missed connections pile up, creating fertile ground for negative comparisons, where one partner begins unfavorably contrasting their spouse with someone new.

Walls, Windows, and the Anatomy of Betrayal

As Wes grew closer to Tess, the divide between him and Rachel widened further. Wes began confiding in Tess about the underlying struggles within his marriage. He also shared a significant professional stressor that he kept entirely hidden from Rachel: he was actively interviewing for a prestigious position at an advertising agency.

When the advertising agency ultimately offered the job to another candidate, Wes returned home visibly devastated. Sensing his profound distress, Rachel gently confronted him, noting that had he shared his ambitions with her, she could have utilized her own background and insights to help him prepare for the interviews. Instead of accepting her support, Wes snapped defensively, telling her that he did not need her help.

The following day, Wes met Tess, who embraced him warmly and offered unreserved praise for his photography work. In that moment of contrast, Tess made Wes feel deeply believed in—a validation he felt was entirely absent in his marriage. In his perception, Tess had suddenly become physically more attractive and significantly kinder than his wife.

Dr. Shirley Glass, a renowned infidelity researcher and author of Not "Just Friends," utilized the metaphors of walls and windows to describe the boundaries of a healthy relationship. In a secure marriage, a protective wall keeps outside influences from invading the couple’s shared emotional core, while a window allows partners to remain completely open, transparent, and vulnerable to one another. Rajendrakumar notes that as an emotional affair develops, the window between primary partners is replaced by a solid wall, while a new window opens outward to an outsider. Secrets, Glass emphasizes, invariably begin with omission. By hiding both his movie outings and his job interviews from Rachel, Wes had effectively constructed a wall between himself and his wife while opening his windows completely to Tess.

Eventually, Wes and Tess transitioned from emotional confidants to romantic lovers. Dr. John Gottman notes in The Seven Principles for Making Marriage Work that while society often views affairs as the root cause of divorce, the reality is frequently the reverse. Underlying problems, unresolved conflicts, and emotional disconnections within a marriage often place a couple on a trajectory toward separation, which in turn drives one or both partners to seek intimate connection externally. Furthermore, Dr. Gottman observes that secret trysts with lovers are rarely driven purely by sex; rather, they represent an underlying quest for friendship, support, understanding, respect, attention, and genuine concern.

Recognizing the Warning Signs and Seeking Recovery

For a long time, nothing in Wes’s initial interactions with Tess resembled infidelity. The transition occurred incrementally: from cheerful advice replacing empathy, to measuring a spouse against a new acquaintance, to hiding social outings, and finally to concealing professional failures. Once Wes began actively concealing the depth of his connection with Tess, his behavior crossed firmly into the territory of emotional cheating.

Experts emphasize that the narrative could easily have unfolded differently. Had Wes initially shared the reality of his vulnerability regarding his struggling photography business and his emotional reaction to Rachel’s rising career, he might have avoided the trap of seeking validation elsewhere. Staying silent systematically denied Rachel the opportunity to offer him love and support.

Missed bids for attention, minor secrets, and fleeting negative comparisons can surface in any long-term marriage without automatically transforming a partner into a cheater. The true danger lies in repetition and accumulation over time. However, couples who recognize these early warning patterns can often intervene and repair the foundation of their relationship before minor emotional drifts escalate into full-scale betrayals.

For partners navigating the aftermath of betrayal or seeking to strengthen their emotional attunement, various clinical resources remain available. The Gottman Institute provides directories of certified couples therapists, and structured relationship frameworks—such as the Trust Revival Method developed by Dr. John and Dr. Julie Gottman—offer pathways through the phases of atonement, attunement, and attachment for relationships working to rebuild trust.
