Lone,

Think of her ring removal as an exercise in futility. It's an unconscious 'freeing' of herself, it's a statement she's making to herself about breaking free of the oppressive bond she felt she had with you. Women are very symbolic...removing her wedding ring can mean any number of things to her today...that will have completely different meanings tomorrow....we can't help it, we're just wired that way.

Leave your ring on as a demonstration of YOUR continued commitment to your marriage...and let her work through her issues, in her own way....

Some of what she'll say and do is absolute craziness, but it's just part of her attempt to discover WHO she is now that she feels a desperate need to be independent...at least for now.

As for her calling to tell you her plans tonight, that's common courtesty, she should have done so, just as you were thoughtful enough to let her know that you'd be working late. It's mutual respect, and that's a beautiful thing.
