truthseeker,
The situation you are in sounds very familiar to mine in many ways. I'm the "opposing husband" (self-titled...she doesn't call me that) and have pointed out many things to her about the witness religion. She is much more reasonable, and she has been making some progress seeing my point of view and actually agreeing to it. It's taken a year or more...plus all the help and advice I could compile from JWD.
She's sticking it out for the good friends she has who know her doubts and how she feels about the hyposcrisy in the WT system. Who knows if they would be good friends if she faded out. I feel in this case, they still would be. Also, she still believes in God and is doing that "waiting on Jehovah" thing while tolerating what she can. She is about 1400 miles from her family and old friends, so she doesn't want to throw away the social network she has right now. She does have a few friends at her work, and we have her family come up and stay for a couple months at a time, but it's not enough for her. She's a little depressed and has another medical issue, so I don't want to push things anymore.
We have a couple very well-balanced elders on our side. So far, we've been left alone. She still wants to go to the book study, but as for the TMS/Service meetings and the Sunday meetings, she rarely attends those.
I feel I'm finally at a good place with her. She doesn't ask me to go to the meetings. Our religious conversations don't explode into arguments. And I have hope that eventually, she'll see the cult for what it is and decide to leave.
It's been a long process, but I think time is on our side. The WT Society will bury itself given enough time.
So my advice is to give it time and patience...don't push too hard or too often. Small acorns grow mighty oaks. (Like my corny "illustration" here?)
I'll be paying close attention to your situation as it parallels my own. So keep us posted, and good luck!
