You need to stop worrying if you W is going to change her mind. That may or may not happen. I still believe it might not. But you cannot count on that, and I think you need to live your life as if it will happen.
I think sharing a credit card at this point is ridiculous and risky. If I was in your shoes (And I was! But we didn't share credit cards, just accounts that were changed) I would cancel that immediately and then nicely present it to my S as something I was doing to help with the D. That I wanted to make the whole thing easier. Yes, that type of stuff did upset my H, but when I was so nice and calm about things and presented it as something I was doing to "help him with the D," he couldn't get so angry (or he might get angry but I stayed calm, positive and just refused to engage in a fight). This definitely made the D, and the consequences of it very real to him.
I don't understand why you moved out of the house. If she was the one who wanted the D why didn't she move out?
There is no arriving, ever. It is all a continual becoming.
