5th, here's how I see it.... if you love your wife and kids then you're doing the best thing you can do being honest with them and trying to get them out of this cult. Good luck...
As for those who say "do nothing" becasue doing what's right definatly causes trouble. Ask them how well that doing nothing stuff is working out for them. How many family members have they freed from the cult? Yea, that doing nothing stuff accomplishes just that.... nothing.
