This is a well-written article and as someone living with BPD I can confirm its accuracy.
I've chosen to remain single for the stability it allows me, which I'm not able to find inside of a romantic relationship. I also have an FP that I no longer speak to and intentionally haven't replaced.
I do believe there is healing that can be done, but have no reason to believe that your statement regarding the ultimate lack of cure is incorrect. I suppose it remains to be seen in my own life.
Thank you for addressing this topic. I write about it as well since I think there's a real lack of helpful information about it.
