Previous research suggests that romantic relationship dissolution diminishes self-concept clarity, leading to emotional distress. Over time, people overcome breakup. But little is known about how people respond to the reduced self-concept clarity that results from this process. The current research examined predictors and mediators of relationship rekindling (desiring to reestablish a relationship with an ex-partner) as a method of navigating self-concept clarity impairment post-dissolution. In two cross-sectional studies, we found that attachment anxiety predicted relationship rekindling both retrospectively (Study 1) and concurrently (Study 2), and this association was mediated by self-concept clarity. These results indicate that anxiously attached individuals may attempt to resolve the substantial self-concept impairment posed by dissolution by reestablishing the relationship with the ex-partner.
