Hi Prisca,
Your story was very heartfelt. I believe you have felt especially upset because this is your sister, your only remaining tie to your immediate family. And, her husband was placing you in a very uneasy position.
You seem to have a very loving and kind nature, to have actually gone to the point you did. I, on the other hand, have not read anything from JW's since leaving. Their whole message has left a very bitter taste in my soul. Like you, however, I will read actual texts from the bible, and especially words that were supposedly spoken by Jesus--just not from any WT literature. (you will notice that I've very cautious and doubtful, even to that point.)
I'm so glad that you stood up for yourself, as these situations are so very stressful. Your neice will probably not remember what happened, but your sister will. And, your brother in law will be forced to respect your opinions.
The problem that continues, is that these people are borg, and they only know one thing. They are programmed that way. BUT, THEY CONTINUE TO ALLOW THEMSELVES to be in the situation they are in. They cannot think for themselves, until such time as they choose to do so. It's so hard to reason with the borg.
When I visited my mom in FL in May of last year, she had it all planned that I would attend a meeting with her. She said, it was the Sunday meeting, and the public attends those anyway, so she REALLY WANTED me to go. It really put me in a spot that I hadn't counted on. I didn't reply to her right away , but told her that I would think about it and let her know. (Of course, I knew I wasn't going in my heart. I don't care if she is my mother, and she's old, and it might have been MY LAST CHANCE.) She was very hurt when I told her I wasn't going. That I had made my break and saw no need to even visit such a place, even for her sake.
It had to be that way for me. Just as it has to be that way for you. No turning back. No waivering, as they will pick up on that and go for hundreds of miles in their minds to get you back.
Take care, and know you aren't alone.
Peace and Love,
Karen/Sentinel
