Belief in romantic destiny holds that potential relationship partners are either meant for each other or they are not. As hypothesized, a longitudinal study of romantic relationships revealed that the relation between initial satisfaction and relationship longevity was stronger for those who believe in romantic destiny. In addition, belief in destiny was associated with avoidance coping strategies in dealing with relationship stressors, and with taking more responsibility for ending the relationship. Belief in growth independently holds that successful relationships ate cultivated and developed, and was associated with long-term approaches to dating, relationship-maintaining coping strategies and, once the relationship had ended, disagreeing that it seemed wrong from the beginning. Implications and future research avenues are discussed.
