Hi Junebugg
Along with
Wendydarling, I welcome you here too

I'm glad that you've reached out to us, and Walking on Eggshells is such a wonderful introductory book on BPD. It certainly validated much for me when I came here 8 months ago after my DD27 cut me and my GD1 out of her life after a terrible rage.
You mention that your daughter ticks all the boxes, are you able to elaborate here? I'm sorry your other daughter was assaulted, that is very difficult to deal with. Safety is paramount and I hope you are able to set some boundaries around this type of behaviour while still being able to validate your daughter's obvious anger.
It sounds like there are some challenges with your husband, denial maybe. I often hear from other parents here that the child with BPD tendencies/diagnosed, often plays one parent over the other. Do you think therapy might be of use to you?
I hope you and your daughter are ok, there's lot's to contend with and the board to the right is very informative.
Look forward to hearing from you
Merlot
