@SillyOldBear - I agree that something lacking in our marriage helped "push" her to seek it elsewhere, hence her EA and subsequent search for "highest, best, self". But her refusal to recognize it and try to work things out is more a result of MLC, rather than my specific actions, IMHO. Her refusal to acknowledge changes I've made and see that things would/will be different in the future and that we could have the marriage she wants is a result of the fog she is now in, as is her inability to foresee the immense damage she will cause and/or has already caused.
I don't doubt that at all, and I'm not trying to blame you anymore than you blame yourself. What I'm trying to say is that the old DB hands would probably advise you, if she were having an affair, that focusing on the other man is a mistake. I would follow that same advice with this goofy life coach guy. He is a symptom, not the disease. He just has a different schtick than the average OM.
