Welcome Lost and Adrift. My heart goes out to you and your beloved partner. I pray for these evil scum-bags to have their little worlds collapse when their "gods" in Brooklyn really start turning the knife in them. They deserve nothing but bad in their lives because of their evil.
I hope many lurkers read your post and perhaps save themselves the heartache you've experienced, simply by following this advice which I'm going to SHOUT out -
NEVER AGREE TO MEET WITH & TALK TO TWO OR MORE APPOINTED MEN!
Why voluntarily walk into a lion's den, when you know that the outcome is a foregone conclusion?
Ask what the reason for the "chat" is, then politely but firmly decline the offer to talk, thanking them for the invitation; "Not at the moment thanks, but I'll let you know."
If they threaten to deal with you in your absence, respond by promising them that you will seek legal redress against the local Body of Elders/Trustees - via the courts/Charities Commission/Human Rights respecting your privacy, data protection, and human rights, if your name is publicly announced (for any reason) within their Kingdom Hall - a venue which is open to all members of the public and is subject to the Charities Commission's laws & regulations!
Potential victims have absolutely nothing to lose by having such a lawyer's letter sent to these reptiles!
I wish you both the very best.
