"did she feel shame"
^^
Yes.
My thoughts:
She knows that you know "her". The parts of her that she really wants not to exist, and is powerless to control. She hates that part of herself and doesn't understand how anyone could care about someone "like that".
Of course, I could be totally wrong. It's useless to speculate about what a person might or might not be thinking.
YES! This is exactly how I'm thinking and trying to rationalise things.
She was always so image conscious and completely obsessed with how the outside world saw her.
Outwardly she was incredibly vein and was quick to expose perceived physical imperfections in others (she spent some effort trying to convince me that I should consider cosmetic surgery for my nose - There is nothing wrong with my nose but she later admitted to hating hers!).
Inwardly she must've been struggling with such pain that she masked it trying to make the outside as 'perfect' as she could and distracted herself by finding fault in others.
Maybe once she could no longer conceal her pain internally and it began creep out, eventually leading to severe cutting episodes, she could no longer hide from herself - Perhaps she manifested the shame she felt in me? Maybe in her mind, she filled my up with so much hate and hurt and sent me packing in the hope that it would rid herself of the same feelings.
I guess maybe one day she'll realize in time that she can project all she wants and load her pain on to others, but this will never leave her free of BPD.
She will hurt for a life time.
I for one, will not.
