One of the misconceptions about DBing, in my opinion, is the "Do what works" thing. The problem is that people mis-define "works" as being "what doesn't make her/him angry" and "what makes her/him act nice towards me." Instead of as "what moves me further along down the path toward a mutually-healthy and committed marriage."
Sometimes one has to take a short-term "hit" in the "nice" department in order to solidify a healthier, longer-term gain.

True, but there certainly is a time and place for taking the bolded path above. Like when the WAS is seriously threatening to start the D process. At this point "what works" is anything that stalls the D process and gives you a little time. Playing hard ball at the wrong time will only move you apart quicker.
I like to think I'm well past that point, and I really think Arsene is too. As far as I'm concerned my D has already been busted. I'm working on building a better marriage for us by working on me, and monitoring results. So, I'd say that "what works" is a process of constant adjustment.
