Before infidelity enters a romantic relationship, there is often a quiet decline in the well-being of both partners. A study conducted by researchers from Tilburg University and reported in the journal Psychological Science explored this pattern, focusing on how relationship health changes over time and how betrayal fits into that arc.
Cheating stands out as one of the leading factors associated with the dissolution of couples. When researchers examine how relationships function, they consistently find links between infidelity and a range of relational problems. Yet the study notes a key question: does infidelity cause these problems, or do existing troubles make cheating more likely? The direction of causality remains debated, underscoring the complexity of intimate dynamics.
The researchers drew on data from a long-running study of close relationships and interpersonal dynamics, spanning many years. In total, more than 12,000 individuals contributed to the dataset. From this pool, two subgroups were identified: pairs in which at least one partner experienced cheating, and a control group consisting of couples who reported no infidelity. Each participant answered a comprehensive questionnaire assessing satisfaction with the relationship, perceived level of conflict, and self-esteem. The questions probed daily interactions, emotional closeness, and the overall sense of security within the partnership.
The analysis revealed that, even before any act of infidelity occurred, reported self-esteem tended to be lower among partners who would later engage in cheating or experience it. Relationship satisfaction and perceived intimacy also trended downward in this group, while conflict tended to increase. These patterns suggest that troubled communication and waning emotional connection may predate betrayal, rather than betrayal appearing as an isolated, stand-alone event in a healthy relationship.
Taken together, the findings point to a broader view: the health of a relationship often reflects ongoing communication dynamics, mutual support, and a shared sense of stability. When those elements deteriorate, the risk of betrayal appears to rise. The study does not deny that cheating can hurt a relationship deeply; instead, it highlights an ongoing cycle where fragile emotional bonds and unresolved issues may set the stage for trust to erode. In such cases, addressing core communication gaps and rebuilding a sense of safety could be crucial steps for couples aiming to prevent or recover from infidelity. Future research continues to explore how partners can recognize early warning signs, seek constructive help, and strengthen the relational foundation to reduce the likelihood of betrayal improving or worsening outcomes for both people involved (Tilburg University study).
Overall, the work emphasizes that infidelity is rarely an isolated incident. It often sits within a broader constellation of relational challenges—communication breakdowns, diminished self-worth, and escalating conflict. Understanding these links can help individuals and couples approach relationship problems with a focus on prevention, early intervention, and healthier ways of handling disagreements. The insight remains valuable for anyone seeking to foster trust and resilience in intimate partnerships.
