Well, I met with the brother and told him that EVERYTHING involving him and my son will and must go through me and that includes the study. He agreed to "back off".
I made the mistake of telling my wife about the conversation. She is not happy. She basically told me that if I was "spiritually strong", no one would have to pick up the slack as far as headship (as seen through the eyes of the witnesses) goes.
It got so bad between us that I spent last night at a motel. Yeah, this religion as done wonders for my family.
