It is very hard for you in this situation, but there comes a time when you can no loger live a lie. Although your daughters may like going to meetings now it's extremely likely they will leave as they get older (66% of those brought up as witnesses leave when they become adults)
Your husband almost certainly likes the power he has in the cong, but sooner or later he will hopefully see the double standards and hypocrisy that goes on in the org. I wish you well.
