I agree that it seems awfully imbalanced in terms of how you both have handled and are handling the changes on both ends. I personally think the comment about you moving on after seeing the new bedspread stems from your last comment to her about not needing to be around to this and that (the comment about new boundaries). She is feeling lack of control and it is scaring the hell out of her! She is panicking, and I honestly don't feel she's behaving this way because she's looking for a way out. I mean, didn't she willingly come over and help you out, cook dinner, etc, when she heard you were sick? Looking in from the outside, Dave, I think she's worried sick that you ARE moving on and she has lost control of the situation.
Hope you're feeling better now and continue to do so. Good idea to wait until you're recovered before making any decisions or taking any actions. Stay strong, and remember your goals and how you can best utilize DB to meet those goals.
