Brother Dan,
Hang in there man. It sounds like you are getting anxious. Remember being a witness is an identity. When you point out that it is all false it can feel like a personal attack and not just an attack on a crooked organization. I agree with undercover that you should not send that email. Don't even keep it on your computer.
Your experience scared the crap out of me because it sounds like the reaction my wife could have if I laid it all out to her in that manner instead of a drip feed.
I am still working on my wife. She knows I have doubts, she has always been my best friend and I have told her point blank that if the elders knew that I did not wholeheartedly believe in many of the doctrines I would be immediately DFed. She can see that there are things that are wrong also but is waiting for a clear sign that God is not with the organization anymore.
She feels that I am confused and stumbled, and that time will be the test as to whether God's spirit is still with the org. So for the moment I am in a holding pattern waiting for something to break loose.
I figure that since it took my whole life to get to where I was in the organization I can't expect to get out too quickly without losing the person I love the most in the world. So I sit in the meetings, give parts, and sometimes go in service all of the time hating myself. But I feel that it is worth hating myself for a short while to save the person I love.
Take care and hang in there. It is rough. I think that your wifes reaction is telling you that you hit a nerve. Let it simmer for a while.
