I am in a very similar position to many of you guys. As an aside, why is it so often the husband who leaves, with the wife still in the organization? Or is this selection bias, maybe only the guys post about it?
Anyways, we've been married 11 years, we have 3 kids, and I have been inactive (the technical Witness definition of inactive) for a little over a year now, though it was token service for the preceding five years. The only reason I still attend is to help my wife with the kids, who she will take there with or without me. I don't comment, I've quit the TMS. I figure that this is kind of a reverse of the Witness strategy of "winning them over without a word." As long as I don't turn into what she perceives as a despicable person, abandoning her with three young children, it might help her to listen when I tell her about the cult.
We have the occasional discussion about it. She's a difficult one, though... she loves "Jehovah" and wants to give something back, she likes a spiritual element in her life, she likes the socialization, she feels a sense of community service when she "preaches," and her whole family is in. She feels like she's doing right by our kids. She really does think it's the best religion, and that association with a religion is necessary.
The weird thing is that she disagrees with many of the Watchtower teachings, she just doesn't CARE whether they're wrong or not. She's very pragmatic and practical about it--whereas I might get all worked up about the principle of a thing, she will just shrug and say that it doesn't matter. Among the things she dislikes or disagrees with: All the shit they make up about Isaiah, Daniel, and Revelation, the constant appeals to loyalty and avoiding independent thinking, some specifics about how the ministry is conducted, how much power individual elders have to ruin people's lives, how they discourage education, the ban on voting, the superior attitude they have about "worldly people," the huge obsession with sex that much of the Watchtower content has, and calling it "The Truth."
So I'm in a position where if I bring something to her attention that I have a huge problem with, she's likely to AGREE with me, and yet not care. How do you work with someone like that?
Anyways just wanted to say that I totally understand where you're coming from on this.
