She is still in therapy and has been for 10 years now.
Good therapists are hard to come by... .plus the patient has to want to find a problem and then actively work at making changes. In my experience pwBPD don't do this. I think that they are not capable.
I sought out the guidance and support of a therapist based on my part in what had happened after my ex ran off with new supply. I embrace good therapy.
My expwBPD went to therapy (I kept suggesting to her and her parents that she go... .) and she apparently just told her therapist lie after lie. She told many lies about me.
She also simply lied by omission (well... if we don't mention a problem there isn't one right.). I see a lot of that being due to massive shame.
I was invited to a "closure" session. (There were supposed to be 6 sessions). Boy did I walk into the gauntlet. My ex plays cute/innocent and tells lies and manipulates. This is just what she had done with the therapist.
(She had cheated on me and run off with new supply a week before Christmas). Her therapist did not know any of this. Her therapist also judged me based on my exe's skewed untruths? (Really bad therapist)...
Basically my ex had set this whole thing up so that I was walking into a bizarre surprise ambush? she is sitting there, telling lies, hanging her head down in shame and the therapist is backing her up and attacking me... .It was bizarre. This woman had just met me that day? I was just stunned... .left there in tears. Did not go back. That was the last time I was in the presence of my ex... .unless she was doing a drive-by

or something.
It's soo sad... .they just go on and on causing mess after mess, believing that it is all someone else's fault. Time after time.
I think my ex thought that she had a successful therapy session? She manipulated it to her advantage... .success, right?
Not sure. I just stay absolute NC for my well being.
