I did a stopped going to meetings as I research and was waking up also work kept me busy. talked to the elders a bit about a couple of subjects and was going to DA. Changed my mind , was publicly reproved and went to one or two meetings after thAt then quit. My wife was thinking I was going to come back until a friend told her I told her that I was fine do to some things I learned. I don't remember if I told the friend this exactly but may have told her about all the child abuse.
Know one comes around and only speak to me if they have to. No friends at all. They came around for the wife to support her for awhile but that has died down. The wife and kids go to most meetings. I'm treated pretty much like the odd man out and I don't matter much to the wife anyway.
If I were you if you can't wake up the wife and depending how old the kids are I would stay in and try to wake the kids and even the wife over time. Bible study showing problems as well as going over the history of the cult I think can help to wake someone up.
Writting to others is a waste of time they make excuses even if your points are valid.
