It's a tough question, Arsene, and I post about this topic -- "how do you define 'working' " -- often.
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.
