Don't give up! Have you started missing meetings yet? I know at the end of my time spent in the meetings, I wanted to scream aloud and run out. I had to slowly fade from meetings and when I did go, I read something else rather than listen. I often read the Bible which irritated those around me.
I couldn't talk to my dub husband about anything either. It is a very discouraging feeling. I took it slow and let him see the extreme emotional pain that I was feeling about the whole situation. I let him know about things that disturbed me one at a time, as he chose to listen.
It may take a lot of time and patience, but we have worked out a peaceful and close relationship. He knows I am on here and also my personal, deep thoughts again. Things can work out and I hope they do for you and your wife.
I do think you need to start missing some meetings before your brain explodes.
