Those with Borderline Personality Disorder – especially if they aren’t getting treatment – not only often discuss their troubled pasts but they are re-living them more often than not. Troubled aspects of the borderline’s past are triggered in many ways but most commonly and most often through attempts to relate to others. This is the primary basis of so much of the behaviour (and often abuse) that family members or relationships partners of those with BPD (non borderlines) see and often have imposed upon them.
