Ugh, I'm sorry. In April I was un-shunned long enough to say my final goodbye to my dying dad with some of my family around and treated like normal family, only to get shunned after leaving hospice. Of course, when my mom needed legal documents signed for the estate or to ask if they could use my name in the memorial talk that's okay. It is all on their terms. They giveth and they taketh away at their whim. It's all about them. My mom said we'd see each other again. I guess maybe when she's in hospice someday? Screw that. We're human beings, not toys to be played with and put away when done.
Walk away and live your life. Don't let yourself get played over and over by their dysfunction. JWs are narcissists. They don't have a clue what love is.
