OMW - from reading all your stuff as you went through it, I think you really are back and forth about what you want from her. When I am feeling angry at my H, I try to think about the other reasons why it is good to stay the DB course, the kids, the money, convenience, improving myself/dealing with his betrayal, avoiding this in future relationships, etc. Sometimes I cannot see myself being happy with him, but deep inside I am pretty sure I can be (or I would never have lasted this long).
These guys have good advice - and I'd add, regardless of what you want in marriage/divorce, you want her to come out of the fog for your D's sake. DBing is good for that.
