Puppy...I do believe there is a distinction between an MLC affair and a straightforward affair.

MLC affair, in my experience, is a way to boost up the rock bottom confidence and a mechanism for escape in the alien land. We are so numb and disengaged from everything around us. We see the OM/OW as a "friend." Whereas a straightforward, non-MLC affair is done for purely selfish reasons which are the addicting behaviors...the need for more dopamine becomes more "urgent". Which is why I think busting this type of affair usually works.

Mind you, I am not minimizing the effect of an affair (EA or PA) on the LBS in any way at all. However, affair exposure WILL not work for the MLC spouse.
