Over a third of individuals with borderline personality disorder (BPD) are in long-term romantic partnerships, yet little is known about the experiences of their partners. Because difficulties in interpersonal relationships are a hallmark of BPD, it is especially important to understand the support needs of their romantic partners. This systematic review investigates the experiences of romantic partners of adult individuals with BPD and the interventions designed to support them. Twenty-two articles were found, 13 of which pertained to partner experiences and 9 to interventions.
