And maybe another peice of advice might be to keep your correspondence limited to those who have a positive attitude, and who have had some successes. Why listen to people who have screwed up. No offense to those folks, I have made many mistakes in this most strangest of journies. But common sense dictates that you talk to those making progress rather than those who might want some company in failure.
Until you read Hassan's book(s), the number one thing I could tell you is that any effort to free your wife from the tower has to be based on trust. If you don't have her trust you will get nowhere. If you don't have her trust, you need to start repairing it. That is all you should work on. It is that important.
How to build trust. Find areas of agreement. Talk to her as a person, not someone you are trying to sell something to. Be genuinely curious as to how/why she is thinking/feeling/concerned about the things she is. Keep calm. Smile. Tell her how much you love her. Validate her intentions in choosing to believe in the jw. They are honorable intentions and should be treated as such. Demand the same for yourself. God gave you a conscience because he expects you to use it. You are using it, and hers is not more important than yours.
