Welcome and sorry you had to get involved with this cult. It's good to hear that you taking care of yourself. I hope that soon your wife will also be able to wake up and both of you can come out together.
What worked for my wife may not work for yours. I started planning weekend getaways that made us miss meetings. I used those opportunities to tell her how I felt about the organization and how depressed I was as an Elder. That seemed to work. I slowly shared little things with her and in time she too woke up. She is still in a bit mentally but she wants to get out and move on as well.
Maybe try to plan things on meeting nights and see how that goes. Have lots of fun together and cement your relationship. Build friendships with outsiders and get close with your "worldly" relatives so you have a support system.
