I didn't mean my comments to be a statment on "to DB or not DB". I just meant that to an observer's eye, she seems to be thrown by the fact that you are surviving and doing fine without her at your side. I do not mean to suggest that you should plot to make yourself unavailable or anything. It was just an observation...
I think you are absolutely right. You have done so much to work on your situation. At this point, what you are doing is real detachment, not forced, manipulative attempts to get her to "miss" you. And, not that it matters, because you aren't "trying" here, but I also think that has a greater effect on your wife b/c she realizes you are actually going about your life WITHOUT worrying about her every move.
