Hugs, gentle ones. Hope that the Tylenol helps.
Aly, we had a similar situation in our family when a parent was dying. One of my siblings did absolutely nothing to help out; nothing. We haven’t seen or heard from that sibling since the funeral and all of our calls and attempts at communication/relationship have been ignored. It hurts.
For my own sanity and happiness, we have to put it aside. The ball is totally outside of our court.
