Hubert's advice, IMO, is advanced
You will know if and when you are ready for such a big step,
but you can at least break some habits, now.
Stop saying "the Truth." Start speaking of the WTS like a
third party instead of like it's "our" organization.
You are the head of household. Make some decisions about the kids.
Such as: If they want to stay home with Dad, let them. If they want to
get involved in some activity; sports, club, hobby- let them. If they want to
have a friend, it's okay (probably avoid the sleep-over thing).
