I agree with what everyone has said so far about headship and yor wife's unreasonableness, but there's one thing I would like to add:
She says that she does not go around looking for support groups that ‘bad mouth' my church or religion so she does not understand why I go to a group that bad mouths the WatchTower Society.
The above statement is a boldfaced lie. The WB&TS trashes your religion and everyone elses's every chance it gets in their so-called literature and meetings.
Hang tough on this. She has no right to demand anything of you; especially if she wants to be a jw. You are the head of your family, so you make the decisions. According to her beliefs, you could be the biggest asshole in the world, and it's her duty to be a submissive wife. Period!
Believe me, I was physically abused and mentally tortured in every way imaginable by my jw husband. The elders made it very clear that I had no right to even demand feeling safe in my own home or car. I lost my family, friends, home and most of my material possessions when I finally insisted on at least being treated like a human being. There are many others like me.
And another thing...I'm sorry if this offends you, but you should think long and hard about your wife's personality. For an adult to be jealous over a parent's relationship with his or her child is beyond ridiulous. I loved my stepkids by virtue of their birth...they have part of my husband, whom I worship. Resenting them would be resenting him, something I could never do. Shame on her for not doing the same for such a loving husband.
