Summary

Same-sex couple relationship maintenance involves the exchange of communication and relational behaviors to sustain these romantic relationships. In communication studies, same-sex couple relationship maintenance began in the late 1990s, and while it remains understudied, research in this area continues to grow and illuminate understanding of how communication plays a central role in the maintenance of same-sex couple relationships. Social exchange, along with minority stress, have been the predominant theoretical frameworks in studies of same-sex couple relationship maintenance. Overall, evidence suggests that relational maintenance behaviors (assurances, shared tasks, openness, positivity, conflict management, advice, and shared networks) are associated with positive relational functioning and quality in same-sex couple relationships. Lesbian, gay, bisexual, transgender, and queer+ (LGBTQ+)-specific relational behaviors, such as being “out” as a couple and seeking out LGBTQ+-supportive environments, also have been highlighted. Research also points to the positive impact of partner social support and same-sex marriage on same-sex couple commitment and satisfaction, and a negative relational impact from concealing LGBTQ+ identity and same-sex relationship status. Future research is needed to continue to illuminate the evolving impact of increasing social legitimacy (e.g., same-sex marriage) on same-sex couple relationship maintenance.
