Say you are a doctor and your wife is the patient. You discover she has cancer. Instead of treating her with the proper chemo and radiation that has a high cure rate, you prescribe an anti-biotic and hope for the best. We all know where that would lead.
I think those of us on this board just see you trying things that aren't really gonna help and looking past the tried and true advice of those of us who have been-there, done-that. I think you are just SOOOOOO close to the situation that you can't see the forest for the trees.
I agree with LFL, fret and worry all you want, but don't let her know it! I know in the past when she felt you pulling away in the slightest, she made some progress. The trick is to not let up, AT ALL. That doesn't mean not having hope or faith. It just means using the RIGHT TOOLS to get there.
