What Do People Do, Say, and Feel When They Have Affairs? Associations between Extradyadic Infidelity Motives with Behavioral, Emotional, and Sexual Outcomes.

In this study, we surveyed a sample of U.S. undergraduates and internet-based participants (N = 495) about their experiences during/after romantic infidelity (affairs), and their initial motivations to engage in infidelity. Meaningful associations emerged between motivation and experience variables. Dyadic motivations (e.g., anger at one's partner, lack of love) were linked with longer affairs, more public dates with affair partners, and primary relationship dissolution. Conversely, non-dyadic situational motivations (e.g., feeling stressed or intoxicated) were linked with shorter affairs, less satisfying sex during affairs, and lower rates of disclosure and dissolution. These findings suggest meaningful infidelity typologies and may aid researchers and practitioners in helping others resolve relational conflicts.
