Liv, the Work in "Loving What Is" hasn't changed my experience living with a P-A NPD man for nearly 20 years. What it changed is how I think about it.
I guess I'd say what Byron Katie's Work has done for me is show me that none of STBXH's stuff is my stuff. He chose to have sex with other women. He chose to break his vows. The fact of me -- no influence.
Hope you are well today. Great news on your new phone, and you are absolutely right -- no explanation needed.
