If you plan on going back and then just fading...that may not work so well now. Seems they have their radar up for that sort of thing. If you then decide to DA, the announcement they now make doesn't make a distinction between the two...they simply announce that you are no longer one of JW's...so you're back in the same boat. No one really knows the reason for your leaving. Even if you fade, most will shun you as you will be regarded as bad association, so there will be little to be gained there. But if you decide to return and go to some meetings and keep up a pretense of being a JW, then you should be fine. If that's what you feel is necessary then by all means do what is best for you.
Hope that helps....
