I am finding that true borderlines never go away... .

I had an encounter recently and it brought me to this website to gain some understanding. I have learned SO MUCH here.
It has been MANY years since our relationship and a couple of years since I have seen her. (Seen and avoided, no contact).
After all these years she saw me in the grocery store (me clueless), ran out of the store with a cart-load with groceries and knew my car and waited near my car for me and then attempted to run into me "by accident"!
It is mind-blowing to me that she thinks I would "chat-it-up" with her after all the horrible instances I have been subjected to. In that instant thank God I had an immediate reaction for self-preservation. Phew!... . it could have been ugly for me.
Just having that happen rocked my emotional boat, big time.
I have to keep telling myself that she is sick and have some empathy, but that should not stop me from protecting me.
