my wife left, but still lives with me

Sorry you find yourself here. Please do post more information. What is the history with you two? What were the problems in the M?

Did you react to her BD at all? Of course you're not supposed to fight it by begging, pleading, etc. But is it possible that she was really looking for you to step up and say you want to save the M? I feel like that is an easy test that can be accomplished without too much further damage.
