Welcome Dreamerdude from the UK!
Now I don't want to be overly optimistic but if your wife is willing to express concerns about GJ at the ARC and being told where to live in Paradise then that is very encouraging.
Often we hear about spouses either literally or metaphorically putting their hands over their ears and screaming or going "lalalala!- I can't hear you!" or running to the elders.
I believe you have a good chance here - but you must fill the vacuum left by leaving this cult - is it friendships/resurrection hope or paradise which holds her?
Think it through - plan treats together and take your time - we all know Armageddy isn't coming soon!
