Hi toddinrochester,
I think that healing is not a linear path and the experience is different for everyone. I contemplated something similar, I believe my exe's authentic self is a good person, mental illness imprisons her.
She gets triggered with stress and intimacy, but I recall moments where things were not always polarized. She's kind, caring and shows compassion.
I would hope that she gets help someday, we have kids and they love their mother unconditionally, I would hope that she would do it for them.
I find BPD is too complicated for me, I can't help her, my love is not above the disorder and I can't cure it.
She has her path, I have my own path, our time is over. I wish her the best.
I prayed for my uBPDex, I let go and let god.
IN BOLD: we all need to realize this. Nons think love can conquer all which leads to our frustrations with the BPD since love is never enough (actually, nothing is ever enough for the BPD).
