From my own experience, it's not only at an end of a relationship, as one doesn't "break up" with or divorce a BPD parent. Some may go no contact but it's not the same. I didn't go NC with my BPD mother. It's about the pwBPD's disordered thinking and feelings in the moment and that to them, feelings feel like facts.
It's splitting, black and white thinking, projection and victim mentality. The end of the relationship can't be about her, she can't be accountable. So it has to be about you, you are the horrible one.
Looking at my situation from childhood on -As kids, we were mostly well behaving, but if BPD mother was upset with us, it was as if we were the worst kids ever. Other times, if she was pleased, she'd compliment me. Hard to believe that but in a way, I think both were true in the moment- it was her emotions that changed in the moment. For someone with BPD- feelings feel like facts.
You were all of it according to her feelings- the best partner ever when she felt it and now, you are the worst person on earth according to her feelings in the moment. But just because someone isn't perfectly wonderful all the time (nobody is) does not mean they are a bad person. Just because your ex says something doesn't make it true.
Imagine she's calling you a pink elephant at the moment. Would you consider her words to be true about you? I don't think so. Neither can her saying it turn you into one.
