The relplies here are all sound especially those that urge caution. It may simplify issues if you ask the question 'What do I want?'
This is a very difficult question so think about carefully.
Lets say that it is to leave the WT and take your wife with you and just fade away. No DF or DA'ing.
If that is what you want then the next question is 'how will I achieve it?'
Firstly, stop stirring the waters and let them settle, never mind 607 and all that, your goal is to fade with your wife, not disprove any doctrines. Keep focused on what you want.
Anything that distracts from your goal, cut it loose. Don't be baited. Use suggestions posted here by others that help.
Write your goal down and when you can reasonably expect to achieve it, then timeline it backwards, 1 year, 6 months, 3 months, 1 month, 3 weeks for example. Work out where you expect to be at each stage and the steps you will take to get there. Check progress regularly and alter your plans/steps etc., as needed.
The main thing is to keep focused and do whatever you have to reach your goal, even if it means having a 'humble attitude'.
Hope it helps.
