I was in an abusive marriage for over a decade. The elders knew about this all along.
My husband continually accused me of cheating on him, if I so much as left the house. I got tired of it and told them I did. I was dying from the years of abuse and walking on eggshells.
They disfellowshipped me and spread rumors that I had gone to live with a boyfriend. I had gone to stay with my mother.
So, disfellowshipped after being a zealous pioneer, do it all the "right way" sister for over 3 decades.
The second level that you find on the board (and happened for me) was when I disfellowshipped myself. The elder's little meeting and shunning is one matter. The individual can still stand in shame at the KH for long enough and be back in. But I started reading the Bible. The real Bible, not the JW Bible. And actually reading it - not just the selected passages from the weekly Watchtower. Someone sent me "Truth or Consequences." My own mother (anointed JW at the time) told me to read "Crisis of Conscience." I just about had a heart attack. But realizing that my treatment was completely unloving, that this group of people accept lies rather than find out the truth, and that their actions did not represent the True God, nor were they in the Bible, I disfellowshipped myself.
I never, ever, ever want to go back!!! (And my mom is a Christian now - praise the Lord!) And to seal the JW fate for me - she disagreed with some of their teachings and is now disfellowshipped at the age of 74, having spent the last 40+ years in the "Truth". Separated from all of her friends, all of her support circle. Who would do that to a 70 year old lady? I've heard rumors spread about her as well - that she must have a boyfriend or something.....
By this all men will know that you are my disciples, if you love one another." - John 13:35.
Conversely, by this alll men will know that you are NOT my disciples, if you hurt one another.
