I'm someone who said that recently so I would like to apologise to you. My post was poorly worded.It's not a trait of BPD. I'm not focusing this at just you but I've noticed a few fraus have suggested Jack may have BPD. As someone with the diagnosis, it's can be quite hurtful, as there seems to be the assumption that people with BPD have no empathy and are manipulative, which is completely untrue. I wouldn't be able to do the job I do if it was.
It is a very misunderstood and stigmatised disorder. People with BPD can infact have a strong sense of empathy; they can empathise with the suffering and also the joy of others. I would never dream of treating people the way Jack does - she is definitely leaning more towards the traits of NPD and HPD than BPD.
What I meant to say was that I do think Jack has a PD (and we can only speculate from the comfort of our armchairs). I mentioned EUPD because (to me) she has an unstable self-image, has trouble in her relationships and there appears to be some (family?) trauma lurking away in the background. What I did NOT mean to imply is that EUPD would be an excuse for her willingness to hurt people or advance herself at the expense of others.
I do apologise if my views came across as ill-informed or as propping up unhelpful stereotypes. Thanks for pulling me up on this x
