One thought on going to the meetings for your wife's sake.
The kids hate it. You hate it. I know you go for her sake, but does that really help? I say this because you may just be keeping her sure that you will one day hear the right talk to bring you back or else something at the meeting will bring you to your senses.
I would consider telling her how much you love her but want to stop going with her to the Kingdom Hall because of the repetitive crap that just isn't true and you want to go do something else with the kids while she's gone.
