Randy,
I was initially very optimistic and worked very hard to apply Hassan's principles with my wife.
Something I have realized is that my wife very desperately NEEDS to believe in the jw. It is more than that she is simply in a mind control situation. Before his methods will work I have to address and help lessen her need.
The other problem I had with Hassan's books is they don't adequately address how significantly more complicated the situation is when you are married to a jw, and have children. It is very difficult to balance the need to gain the trust of your cult member spouse with the need to protect your children from the indoctrination. I have had to make a very difficult decision to focus on protecting my children even if it means damaging trust with my wife.
Other than that, those books are invaluable!!! Read them, read them, digest them, read them again. Practice, practice practice!!! Look at every encounter with a dub as an opportunity to hone your cult-busting skills.
