You sound grounded, like you are making decisions with your mind not your feelings. That is a good thing.
One suggestion, this is something I am working to achieve, try to stop anticipating what will happen with your W in the coming days. I find that when I anticipate something, if it does not occur, it triggers bad emotions. Problem with that is, then I start acting from emotion instead of from reason. It matters a little less for me since H is not around. In your situation, you W is still in the house, providing opportunities for things to go wrong if this happens.
Try to stay in the present only and make decisions based on your thoughts and reason. If this is a habit, and you are not "expecting" her to do or say something, she cannot throw you for a loop.
Easier said than done, as is the case with most of the DB techniques.
