IMO the difference is that you are not in full in-house separation mode yet. She has thrown out the words and there has been no additional conversation and she has not done anything to move the situation forward.
Again what you do doesn't change. Your actions are still the same as what has been outlined previously by many posters.
I still see you so concerned about her every move and interaction. Working on yourself and becoming in-different will help you in the future so you can eliminate the need to be co-dependent.
