Dyadic Adjustment

The purpose of this randomized controlled trial is to evaluate whether a psychodrama group therapy intervention can reduce unresolved breakup distress and improve dyadic adjustment in adults currently involved in romantic relationships who have experienced a significant previous breakup. The main questions this study aims to answer are: * Does participation in psychodrama group therapy reduce breakup distress compared with a waiting-list control condition? * Does participation in psychodrama group therapy improve dyadic adjustment and relationship functioning compared with a waiting-list control condition? The researchers will compare participants receiving the psychodrama group therapy intervention with participants in a waiting-list control condition to determine whether the intervention leads to greater improvements in breakup distress, dyadic adjustment, psychological functioning, relationship quality, and sexual satisfaction. Participants will: * complete assessments at baseline, 16 weeks, and 42 weeks; * participate in a 15-session weekly psychodrama group therapy program (intervention group only); * complete questionnaires assessing breakup distress, dyadic adjustment, psychological outcomes, relationship quality, and sexual satisfaction.
