Take care of yourself and trust your feelings.
Sounds like she's really all about herself and getting back into comfort zone.
Still thinking about the downsizing or do you have another plan?
You are right--as a recovered alcoholic, I can tell you one week is nothing.

Be very wary, as others have said, about allowing that.
Good job holding the line and taking care of your needs in this situation in a compassionate way.
