She has done this to me now for decades that it is like a scar that heals and then she opens it again. When my parents were dying she gave me a blow by blow account by text of another relative dying of cancer. It really upset me to the point I asked her to stop as I was dealing with my own grief at the time. A final break is, for me, the only way to go. She brings me no joy and my whole family dread it when she says she is coming. I am too old and too fragile now to be confronted with yet another sanctimonious blow by blow account of all the personal issues of other family members. It's their business and private to them and should remain so.
Well, well done you! This is more insightful than your original post.
It does sound as if you have made your mind up so stick to your guns. This person sounds like a real pain in the neck so I hope she no longer bothers you and you're free of her insensitivity and pettiness.
