Wow what a lot of information and personal experiences - good for this board! This is exactly why I come here. To learn from others.
Billzfan,
I faded over the course of a few years. It was the cause of many many arguments and some non-speaking days and some sleeping by myself. I have children living at home.
I went very slow. I gave her time to adjust to each new step. She realized pretty quickly what was happening and didn't much like it. I was very concerned that she was going to leave me. We discussed it and she told me that she wouldn't leave.
I relaxed some after that but I know she could change or be influenced by others to change her mind on that at any point.
I started out telling her what I was finding out and how blown away I was by all the information I found that I had no idea existed. That went over like a lead balloon. She would listen to me with her mouth gaping open and she couldn't believe it either. Then when I was finished speaking she'd say that I was negative and she didn't like to hear negativity.
I soon learned to keep my mouth shut.
I haven't attended meetings for some time now. We have developed a don't ask don't tell policy. I don't tell her how I feel about the organization and she doesn't tell me how she feels about me not going. Occasionally something will erupt and we'll have an argument, but that is the exception not the rule.
However, I do realize that her deep abiding love for me has waned. We are married because she took a vow, we have kids and I provide for the family. We're not married because she enjoys being with me or because we communicate so well. We really don't have the kind of quality relationship I'd hoped I would have with my spouse. I'm hanging in there because I want to save my kids. Maybe she'll eventually leave and maybe not, but I want to save my kids.
My kids do sports, have worldly friends, etc etc. It helps balance them. Make sure they understand that God doesn't hate everyone not a witness and that many people can love God and be good people yet never be a witness. And most importantly, love your children unconditionally!
Good luck. pm me anytime.
