In romantic relationships, fidelity and trust are fundamental building blocks for most people. However, fidelity is not a fixed universal rule but rather an extension of the specific boundaries between two individuals. The violation of these boundaries (infidelity) is not merely an ethical issue but also a complex psychological phenomenon involving emotional, cognitive, and behavioral processes.
Psychological research has revealed that cheating is not only linked to ‘betrayal’ but also to deep psychological variables such as attachment, self-esteem, impulse control, and relationship satisfaction (O’Sullivan & Belu, 2022). This article examines the causes, forms, consequences, and ways to heal from cheating in romantic relationships through the lens of scientific research.
Definition and Types of Infidelity
Infidelity can be defined as a breach of the fidelity agreement made with one’s partner. This breach can take physical (sexual contact), emotional (romantic attachment), or virtual (online flirting or secret messaging) forms (Barta & Kiene, 2005).
In today’s digital age, interactions on virtual platforms have blurred the boundaries of emotional infidelity (Whitty, 2003).
Cultural context is also important; what individuals perceive as cheating varies according to cultural norms and personality traits. For example, individuals with high levels of the dark triad traits (narcissism, psychopathy, Machiavellianism) may view infidelity as less of a moral issue.
Reasons for Infidelity
In scientific literature, the reasons for infidelity are generally examined under three main categories: individual characteristics, relationship dynamics, and contextual opportunities (O’Sullivan & Belu, 2022).
1. Individual Characteristics
Personality strongly influences the tendency to cheat. Research shows that individuals with low conscientiousness, low agreeableness, and high extraversion are more prone to cheating (Schmitt, 2004). Furthermore, individuals with an anxious attachment style are more likely to seek emotional validation elsewhere (Birnbaum, 2018).
2. Relationship Dynamics
Low relationship satisfaction, sexual dissatisfaction, and communication problems are strong predictors of infidelity. A longitudinal study conducted in 2022 found that relationship satisfaction declined significantly in the periods preceding infidelity (Stavrova, 2022). This finding suggests that infidelity is often a consequence of relationship problems rather than a cause.
3. Contextual Factors
Opportunity factors are also decisive. Close interaction with the opposite sex in the workplace, frequent travel, or occupations involving high social contact can increase the risk of infidelity (Allen et al., 2005). Furthermore, online environments have expanded the perception of opportunity by creating new ‘emotional alternatives’ (Rodrigues et al., 2021).
The Psychological and Relational Effects of Infidelity
Infidelity affects not only the person who has been cheated on, but also the individual who committed the infidelity and the relationship system as a whole.
The betrayed individual often experiences post-traumatic stress symptoms, depressive mood, anxiety, and loss of self-esteem (Ortman, 2009). Some studies suggest that the experience of being betrayed is even associated with long-term health problems (Roese et al., 2023).
On the other hand, some individuals who commit infidelity do not feel remorse. According to a study from Johns Hopkins University, many people still consider their relationships “healthy” even after infidelity (Lammers et al., 2023). This finding suggests that some individuals rationalize their behavior to reduce cognitive dissonance.
At the relationship level, shaken trust, weakened bonds, and decreased relationship satisfaction are frequently reported (Drigotas et al., 1999). However, it is noteworthy that some couples can rebuild their relationship through the right processes (Gordon et al., 2004).
Recovery and Rebuilding Trust
The recovery process following infidelity is lengthy, emotionally challenging, yet possible. Successful repair typically consists of three fundamental stages: confession and acceptance, emotional processing, and rebuilding the bond (Gordon et al., 2004).
One of the most effective approaches in this process is Emotionally Focused Therapy (EFT). This therapy helps couples repair their emotional bonds after infidelity and rebuild trust (Johnson, 2019).
Open communication, taking responsibility, developing empathy, and rebuilding trust over time are indispensable elements of repair. Furthermore, increasing positive interactions in the relationship (spending quality time together, shared goals, emotional support) acts as a powerful buffer that reduces the risk of future infidelity (Mark et al., 2011).
Conclusion
Infidelity in romantic relationships is not merely an individual act of “betrayal”; it is a multi-layered phenomenon arising from the interaction of personality, attachment, opportunity, and relationship satisfaction.
The damage caused by infidelity at both the individual and relational levels can be profound, but repair is possible with the right psychological interventions.
Research indicates that regaining trust depends on time and stability; while infidelity is a destructive event for relationships, it can sometimes also serve as a turning point for emotional awareness and growth (Johnson, 2019).
