I know this is damned difficult, but you really should have no regrets. I went back just now and read ALL of your old posts, including your original ones, just to make sure I had your sitch correctly in my mind. What I see is a man who was already trying everything (including just about the entire repertoire of the "gentler" approach) when you first came to us, and has subsequently tried most of the "harder" things as well.
Sadly, LBSs and almost LBSs have to realize that we don't control their ultimate decisions.
All we can obviously do is go by what you post to us here, but my reading (and re-reading) of your pretty thorough accounts are of a wife who was already deep into this whole "Law of Attraction" crap by the time you came to us, and who wasn't responding one whit to your patient/understanding/placating approaches.
I really think you've tried just about everything you could, from the whole gamut of techniques.
