Infidelity Decision‐Making by Emerging Adult Women: A Grounded Theory

Year: 2026

Type: article

Abstract: Though infidelity's causes and consequences are widely discussed, the decision-making processes, especially among women, has been largely neglected in the academic literature. This study aims to address this gap by examining the infidelity decision-making process of emerging adult women. Using a constructivist grounded theory approach, we analyzed in-depth, semi-structured interviews with 22 women who had engaged in infidelity while in committed heterosexual relationships. In contrast with more linear decision-making models, the findings reveal that women's infidelity decision-making is a non-linear process involving a dynamic interaction of three interconnected factors-unfulfilling relationship, motivation, and rationalizing-which we illustrate as interlocking gears to emphasize their synchronous and interdependent relationship. This grounded theory expands understanding of infidelity decision-making by moving beyond the constraints of linear models and male-oriented perspectives. Clinically, the findings highlight the importance of both relational dynamics and individual psychological processes when working with clients on infidelity-related issues.
