My situation is a bit different than someone like OTWO or others...
My wife is actually inactive...but is not free of the guilt/fear/control. She defends the WTS when push comes to shove.
I had hoped that being away from the constant indoctrination over time would free her mind to start to see through it on her own. She's smart, bright and logical...in most things anyway. We've had discussions about my issues over the WTS...usually not ending so well.
Over that time though she has kind of created her own version of being a JW. She may defend the hard core doctrines, yet she has become every bit as "worldly" as I have. It's amazing to see how far she's come as far as acting as a regular "worldly" person, yet identifying herself as a Witness. Stripping it to the core of the issue I have to admit that she's quite hypocritical. Defends the WTS, accepts it, yet doesn't follow their counsel/rules, doesn't keep up with serving them, doesn't have a clue about new doctrinal changes.
When I think we've turned a corner and she is finally to a point where freedom of her mind from WT control is imminent, something happens that creates guilt in her and she defends them to the hilt.
I think she actually shuts the conflict out of her mind. Discussions we've had in the past where I've made my position clear or I've cast reasonable doubt on a doctrine is forgotten and at times, we rehash the same things covered before.
Watching her day to day and then seeing a different person emerge when anything WT related is discussed proves to me that this religion is a cult. I can actually see her eyes change. I can see the smart, logical woman change to a zombie robot repeating buzzwords and WT propaganda.
I've tried the head-on approach, the sneaky sideways approach, the drop a hint here and there approach. So far none of it seems to have really made an impact. Which also proves the point that as long as someone wants to believe something they'll find a way to believe...contrary to any evidence presented that undermines the authority of that belief system.
For the most part the subject of JWs/WTS is the 800lb gorilla in the room. He's sitting in the corner quietly eating his bananas, but who knows when he's gonna go ape shit and throw down on something. We don't discuss it much. But when it does come up, it's a doozy.
edited to add: I have to admit, just having her physically free is something. When I first joined here, we were both active, though irregular. As I faded, she fell off attending and hasn't attended in sometime. I'm free mentally and physically. I've got her physically free... I just got to get her to think for herself in this area.
