I am so sorry to hear about your sitch! It's similar to mine but my wife doesn't think she is depressed and won't even consider getting help for it (says she is finally awake). Many of the things your wife said are the same as mine and many others but that doesn't make it any easier to hear. Sometime I wonder if there is a script they all get when starting an EA/PA.
Stay strong, work on you 180's and GAL. I will keep you in my thoughts!
