Hi Purplemoon27,

I’m so sorry that you’re going through this. What a tough spot to be in with your D and her H.
I started out by using the S.E.T. method of talking with my daughter. Initially it irritated me to have change MYSELF yet again for her. So no it didn't work right away but I kept at it. now we are in a nice calm.
I had similar as bluek9 you can’t control others around you what you can control is ho you act and react to them. When you take on the task to change and it’s not easy but it’s not impossible a really I retesting thing happens - when you change everything changes.
Keep learning about BPD it’s a persecution complex where the person really believes that their circumstances are not by their or or lack of good decision, they think that it is caused by circumstances other than themselves. Also I was thinking that BPD is an emotional dysregulation disorder a pwBPD can’t regulate or self sooth and she could be looking for soothing too with baiting and trying to pick fights - my point is be wary of that learn to depersonalize these behaviours it’s the nature of the disorder it’s something that she’s going through, learn to become indifferent to her behaviours you neither like it or hate it emotionally detach from her behaviours.
Your D has a point you have the right to feel the way that you do but I don’t agree with her expectation with being validated for that anger. I’d suggest to put a boundary on yourself with what I said about depersonalizations when she’s emotionally dysregulated it’s directed at the people that are closest to a pwBPD because they are the most tempered change the tempo by finding something else to do to remove yourself from the situation go out and run an errand, go out the garage clean your car, go out and do some yard work I’m sure others can help you with suggestions. Tell her “I’m not to be spoken to in this manner and walk out” As stated previously you can’t change gore she acts you can change how you react to it get out of harms way when she’s acting like this.
Going back to what your D said you have a right to feel your feelings too come here vent on the boards and share with us, use the boards as a place to write down all of the angst, frustration, disappointment, sadness etc... .it’s very therapeutic it helps to talk.
