I don't want to go behind her back, but I thought of calling a particular co-worker and getting her opinion. If she found out though, I think I would be in major trouble, but not too sure I care about that, more for her.
Not sure if this is a wise decision. Have you been a pretty controlling person in the past? Taking initiative in this regard, though helpful and thoughtful from your POV, may not be looked upon favorably by W. Work on this together, and if she doesn't get any better or work any harder as time goes on and you continue to piece your M back together, maybe you can take more of a firm stance (because as SDFoundGirl said, by then you can likely express some of your needs, concerns, etc). Just really be cautious, Atlas. You and I and everyone else here knows she needs some help, but take it easy on getting her there.
Everything else sounds great! Vacation for just the two of you coming from her mouth. You must be doing some serious heel-clicking to that! (I'm so jealous!!! )
