Count me in as one who agrees with your decision to stay away from these toxic people- including your mother. FWIW: My experience was a little different yet may be helpful in this discussion.
Hubby and I are both only children. My when the time came that my mother needed care we were still active JWs. We went into deep debt in order to purchase a house that would be suitable for her needs.( Extra bedroom, wheelchair friendly, etc.)
She was an absolute ungrateful bit#h in every way and to top it off had dementia. She was impossible to live with. After a while, she declared that she didn't want to be cared for by us anymore! Goody! We put her in a nice rest home where her two brothers lived. The problem? It is expensive. She had squandered her multi-million dollar inheritance and was broke. So we paid for her care until we ourselves had to go bankrupt!
At this point, hubby, who was an ex Bethelite and knew some big wigs personally, wrote HQ a lovely letter explaining that Mom had been a faithful JW since she was baptized in 1937 at the same Seattle convention as WBTS president Max Larson. That she had been on a first name basis with Ted Jaracz, and over the years, her family had outright DONATED 7 figures of CASH to the WBTS. In addition, she had given a conditional LOAN from the LAST of her money. (he provided a copy of the loan on WT letterhead.doc
All we were asking for was for WTBTS to REPAY THE LAST MONEY SHE LOANED THEM.
He wrote 3 letters with NO response so he called the desk asking if the letters had been received. The answer was: Yes, they received them. BUT she had (in her demented state) verbally "forgiven the loan" "Put her on welfare" We were forced to do just that.
When she finally died, nobody told me until a week later. (we had left Watchtower and were being shunned by our ENTIRE extended families even though we weren't Dfed or DAed. When hubby asked the lady at the funeral home "Why didn't anyone tell my wife that her mother died?" Her response was, "The ladies from her church said she had NO children." (I personally knew most of the congregation)
Moral of the story: The GB are assholes. Their policies are greedy and self-serving. They produce followers just like them. They are Toxic as a whole. If you are dead to them they should be the same to you. Being a martyr teaches them NOTHING. Stay away from poison.
