PS I think that part of real detachment is actually coming to not care as much about it all. For a long time we are very bound up emotionally with all of this - MLC is like a grip on us, and we have to find ways of letting our spouse go.
I still love what we had, and who he was, but the man who could inflict such hurt on pain on his family? Until he deals with that I don't think I really want him in my life. Someone wisely said 'Love them from afar and in your heart' and it is wise counsel.
