She’s a classic example of the Histrionic Personality Disorder which falls in the Cluster B Personality Disorder spectrum of which BPD is a part.

Women with HPD typically get misbranded a BPD because BPD is the more well known of the two conditions but HPD’s difference is that they tend to be non violent (when female) don’t self injure (as they lean more towards a narcissistic image centric focus as people) and the main aspect of their personalities is being dramatic and the center of attention. They tend not to rage at lover’s unexpectadly like BPD’s rather their anger is turned inwards at themselves if I remember the research correctly.

And they don’t really make their lover’s walk on eggshells fearful of saying this or that like the BPD’s do rather the main way HPD’s victimize people is the old push pull game of the NPD’s…they “love bomb” their targets with incessant praise and make you really feel like a god in their eyes and then when you return the love that they claim they’ve wanted their entire life it flips a switch in their minds that tells them that they both don’t deserve that love and they proceed to lose all feeling for you.

Then you are painted black and you chase them trying to figure out what happened and get your source of (narcissitic) love back.

The dramas they act out with their lovers is similar to how they and BPD’s were both somehow abandoned in childhood by a parental figure not expressing the appropriate empathy from which they could learn it and to become normal human beings.
