Hi Parrots555,
I have read Understanding the Borderline Mother, and suggest you check it out if you haven't already.
It sounds like your mom has shifted from what the book describes as a "Witch or Queen" to "Waif" like behavior. The fourth type in the book is "Hermit".
I think that your mom is taking on the "type" that is serving her needs best...getting her what she wants...at the moment.
I would describe my partner's undiagnosed BPD ex-wife as primarily a Queen (bossy, bullying etc) but if that didn't work for her and she didn't get what she wanted, she would switch to Waif behaviors (the victim, poor poor pitiful her).
I also see all of the types mentioned in the Borderline Mother being tied to what we call FOG (Fear, Obligation, Guilt). How the BPD behaviors are used to get others to do what they want.
(One Panda's opinion) The Witch primarily uses Fear, the Queen can use all three Fear, Obligation, Guilt, the Waif uses Obligation, Guilt and the Hermit probably all three.

Where are things now with your mom, do you have contact with her?
