That sounds absolutely miserable. I'm so sorry. You deserve better treatment than that. Would it be possible to get into marriage counseling? I know that's an up-hill battle (one I've lost with my wife) but maybe getting therapy for yourself would help you to learn ways to improve the communication. Just an idea.
I hope you're able to get some improvement. haha perhaps leaving out the recent Awake (I think) article on the silent treatment. His own all-powerful cult condemns his actions, even. If that's how he's been treating you for any length of time, I'm surprised at how benign your complaint is. You're in a terribly difficult situation and the one person that you ought to be closest too has cut you off. It's not fair and it's definitely not deserved. I'm so sorry to hear how difficult this is for you.
