Not posting for sympathy or advice. Just like knowing that there are a bunch of people here that really understand. I don't have anyone I know that really gets what it is like having a relationship with a pwBPD.
I am balancing trying not to trigger friend pwBPD against me because of potential implications at work. So I had been taking tact of only responding to her texts and messages when she asks me something or making very short comment in reply to her texts and messages. I had ceased setting up any social outings with her or proactively communicating. It had been working quite well for me as it didn't seem to trigger her and I was less and less in her life. then she made plans for my birthday which I accepted so as not to slight her. She treated me like when she first befriended me years ago---super charming, considerate, thoughtful. There was a moment when we were together at dinner when it looked like 'dragon lady' might come out. Her demeanor changed dramatically and I often notice that the look in her eyes changes when she is triggered or splitting me. I took picture of her at that moment under guise of taking photo of her doing a birthday toast. interesting thing is that when she sent the picture to her sister, the sister commented on how her eyes seemed like she was very tired or sick.
Overall, i think she kept me in the white. It had been a very long time since I had been treated like that from her. I had a flash back to how I got sucked in to begin with, but this time with the knowledge of the BPD dynamic. I was much more in tune with her mirroring me and talking about things I care about that I know she hasn't in the past but seemed to now have an interest. It is very fascinating now that I understand a bit more about the disorder.
I am still maintaining my strategy of keeping distance. The white paint hasn't dripped off me yet but fully expecting the broad brush stroke of black to come unannounced.
