it's not the tone (although you're right in that I said that word, once) so much as It's that you actively don't follow the DB advice and you don't admit it.
Is there one DB advice?
I thought the fundamental principle of "DBing" is "do what works, reject what doesn't work".
This follows that what is DB in one situation will not be DB in another, depending on the effectiveness of the approach.
I have never seen anything "work" in a situation with an adulterous wife where the husband didn't take a very strong stand against the lies, drama, cake eating and parasitism that invariably accompanies an affair not to mention the cheating itself.
Wont Stop, in my view and in my experience, this affair your Mrs. is engaged in will not stop unless/until she unterstands what life without you is really like. Her moving out, and no contact with you would likely accomplish this. Lovingly separating (getting her out) and pitch, uttermost darkness will show her what I am referring to.
I am very sure she isn't "done" with you but you do really need to get lovingly ruthless here.
Not easy but absolutely necessary.
