Dear Red,
Thanks for working at this posting thing till you succeeded.
My first husband was, unlike your husband, a total drug taking jerk Ministerial Servant (until I told the elders about the drugs.) He had been privately & publicly reproved at least once a year for 8 yrs. then DF. I continued - that's what I felt it was my duty to do - with all 3 little children. It was hard. But I did it until I didn't want to do it anymore. And it took me a long time to get to that crux point.
For companionship? You can still have a good marriage, not the 3-fold cord we have been taught by the WT, but the 3-fold cord taught by the Bible. You can still put Jehovah God in your life and marriage - perhaps your husband just wants the WTBTS out of it. I'm sorry you have to go through this, it is hard.
Perhaps your husband has some legitimate concerns - have you talked with him quietly, without emotion - if possible? We teach our studies to do that with mates that don't agree with their study of the Bible.
Your husband probably won't respond as you wish - they never do. But the open communication can be a start to a better friendship.
No matter what happens, find your own peace.
