Denton - I understand your frustration. I am in a similar boat as my W moved out a little less than six months ago and I have not seen much progress, partly because of my actions since the bomb and partly because there is an OM involved (and we don't have kids so we don't see each other often).
I also looked at the marriage builders forum and noticed that the principles they discuss there appear to be nearly a 180 from what DB principles advocate.
If you look at my thread, I also thought about exposing to work mates, family, etc. because I thought that would be the only way that W could see the consequences of her actions, but the advice I got here very much discouraged it.
I thought about doing it not out of spite, but because I thought it was the only thing that would stop it...but I have chosen not to do this at this time.
Seems to be a lot of debate on whether or not this is the right course of action across sites, but DB'ing seems to discourage it and rather place the focus on yourself through 180s and GAL'ing.
