I was doing well going dark for about a week but I felt like it was coming off more as anger than detaching. So like always throughout our marrige I caved in first ...
Don't look at it as caving so much as just trying something different. The nature of DB'ing is to try something (usually for at least a few weeks) and if you don't see progress then try something else. It sounds like your latter approach worked better? Do what works, discard what doesn't work.
