Background: Romantic relationships are one of the most interesting areas of interpersonal functioning in people with borderline personality. The aim of this narrative review was to synthesise empirical findings on this issue. Sampling and Methods: The PubMed and PsycINFO databases were searched for pertinent materials published between 1980 and March 2016. Thirty articles met the inclusion criteria. Results: Several longitudinal and cross-sectional studies showed that people with borderline personality disorder (BPD) or BPD traits had more - but less prolonged - romantic relationships than people without BPD. The stable relationships of people with BPD or with BPD traits were also less satisfying and more hostile than those of people without BPD. People with BPD or BPD traits had relationships characterised by insecure attachment and passive-aggressive communications. Personality disorders and anxious attachment were more prevalent among the partners of people with BPD or with BPD traits when compared with partners of people without BPD. Conclusion: Unstable and chaotic romantic relationships are at the core of interpersonal dysfunction in BPD. More longitudinal research is needed to delineate the relationship between BPD symptoms and romantic relationship dysfunction, including the modulating role of the partner's clinical features in such an association.
