BPD comes in two flavors. The first, acting out, is the stereotypical BPD that is the better known variety. The second, acting in or quiet BPD, is less well known. For someone in a relationship where it seems to rhyme but not fit understanding the two flavors can be eye opening. There is also some exploration of the relationship between BPD and trauma as most people with BPD have a history of trauma. There may be some gender bias when diagnosing BPD. Men who report the same symptoms as women are more likely to be diagnosed with PTSD than BPD.
