Ever seen pwBPD "get it"?

Has anybody ever experienced a pwBPD start to "get it"? I had a serious and fairly vulnerable conversation with my "officially" undiagnosed stbExW earlier this week. It had been about a month since we last communicated. On her own (meaning: no prompting from me, no talk of BPD, etc) started making statements about how she feels deep emptiness, pointed to ways I had triggered what was clearly a fear of abandonment ("you threw me out like trash" and "You disposed of me" in reference is a fairly minor disagreement and some space taken to cool off), and referred to herself as a "little girl desperate to do anything to make herself feel whole" as she identified her own patterns of acting out, betrayal in our marriage etc. Also made statements like "I don't even know who I am anymore."

She's pushed back against a formal diagnosis of BPD, but it seems she's suddenly learned and is using language right out of the "handbook."

To be clear, these statements were NOT tied to any hoover attempt, pleas for forgiveness or anything of the sort. Just what appeared to be genuine self-reflection.

Anybody had a pwBPD see the light, or at least start to recognize their patterns in a seemingly healthy way?
