Across three studies (total N = 993) with diverse methodologies (i.e., experimental studies, longitudinal in vivo sampling), we found that there are distinct reasons why individuals believe their romantic relationship will become, or did become, less committed, and reasons why individuals believe their relationships will become, or became, more committed. Whereas the strongest endorsed reasons to stay (e.g., satisfaction) are the same as the strongest endorsed reasons to leave (e.g., dissatisfaction), there are many constructs that are more strongly endorsed as either leave reasons (e.g., quality of alternatives) or stay reasons (e.g., love). These reasons are important glimpses into the process that occurs when someone is deciding whether to stay or leave a relationship, and results empirically confirm a core tenet of Interdependence Theory that until now has been only theoretical (i.e., some outcomes contribute more motivation to staying in the current relationship, whereas others contribute more motivation to leaving).

在三项研究中（总共N= 993）通过不同的方法（即实验研究、纵向体内采样），我们发现个人认为他们的浪漫关系会变得或确实变得不那么忠诚的原因是明显的，以及个人认为他们的关系会变得不那么忠诚的原因，或者变得更加投入。虽然最强烈的支持留下理由（例如，满意）与最强烈支持的离开理由（例如，不满意）相同，但有许多结构被更强烈地支持为离开理由（例如，替代品的质量）或留下原因（例如，爱）。这些原因是对某人决定是留下还是离开关系时发生的过程的重要一瞥，
