Thanks Mark 🙂 Yes I remind sister 2 often that I love her, and provide her tons of emotional support.  I never speak badly about sister 1 to her; not one mean word.  I did not explain to her the details of my fight with sister 1 but gave a broad overview, and basically told her that I was putting myself and my husband first, and was doing it for my mental health (I have been much mentally and physically healthier in the past few years) and she seemed to understand.
