I think, that most places I have read about, being "seperated" in the same house is NOT living apart.
I agree. And she had you served while she was standing right there? What? Can't say I've ever heard a story like this. You handled it very well.
Honestly, I think living on her own might be a good reality check for your W. Hopefully she can't go all the way through with a D without ever leaving your house...
All it takes is one time where she says "I changed my mind" then what... oh ok... this is so mind boggling!
