Wow Driving force, if my wife was doing that to me I would let her have it with guns blazing. I would wait till she went into a room and I would go in behind her block the door and use the Bible to show her that were not supposed to judge, exalt ourselves, or shun people. We're supposed to have love, love before faith even. I would make sure I got the point across that she is not a follower of Christ therefore not a follower of God. If she didn't change her attitude I would kick her out.
She may change her tune after this. My wife threatened no sex and the spiritual indangerment card but when those threats didn't work she backed down. It's hard for them when you don't go off the rails and start doing drugs or something like the way the borg says will happen with all who leave Jehovah.
