I am sorry you are having a tough time.
You have posted that your little ones are 6, 9, and 11 and that your wife is from a very judgemental family but yet they are very spiritual.
Are you sure your not the nice guy that married a bit+h but you are too kind hearted to want to acknowledge it? Do you need to save your children from your wife and her family and the religion too? That is a lot to handle for sure.
My elder husband who everyone thought was so spiritual tried to kill me several times. I thought...No. He didn't mean that... And let it pass away from my mind. I know how loveable I am ... so of course he didn't calculate and plan it. It was so confusing. My mind wouldn't, couldn't accept it.
For the sake of your little ones... who need to be in a healthy environment, they need to be in after school activities. They need to be around normal people.
If you ask me as a born in too, like you, what would I start changing with children? Do not allow them to go to meetings during the week. They need sports, do their homework, play, eat and sleep yes, even down time to rest and think. Chores? Sure. Animal care? Sure. Help them to be normal.
No door to door to strangers with a little suit, a big plastered on happy smile, with humiliating dumbed down religious trash. Children need to learn personal boundaries. Religion is one of them.
How are children to learn Stranger - Danger? when their parents take them around strangers all of the time?
How many child abusers do you have in your Hall? Do you know? Of course you don't!
My home congo was filled with sick ooze. Pedophiles, adultery... And who by??? The leaders in the Hall. Some were like sleepers, but others were the ones in leadership positions and pioneers, raising their self-righteous hands and looking down at others. "They were white washed graves... ".
I am sorry. I do not mean to be harsh. I also don't recall if you are an elder... which your wife certainally would not want her "position" as an elder's wife taken away from her.
You are in a tough spot. I feel for you. Keep reading. Keep posting. This is our Worldwide Brotherhood Therapy Class.
