I know what you mean about ignoring the phone calls, it seems impolite not to answer. Try to remember you explained yourself and in fact she is being rude by ignoring your stated wishes.
She is testing you to see if you are still on the line. Sadly, it's only when she thinks you are not that things might change.
Reading your updates reminds me of a time this past summer when my WW, while stretched out on a beach chair, explained to me she felt as though 'the law of attraction' was making everything happen for her through the power of her intention. That was her description of what it felt like to be gorging on cake and having it too. The whole time I sat and listened, stunned she couldn't see I was responsible for serving the cake not the 'universe'.
That's how deluded it can get. You are in the process of defogging her right now. Keep up the good work.
