She is conflicted. That is why she is so wishy washy. That is a good thing. To be clear, there is NO "working on it" while she is still having an A. Until then, nothing that you do matters. I would encourage you to get her out of the house. Let her move into the hotel. This will allow you some piece and the time/space to work on YOU. She will be miserable when she moves out. Let her be. Dont concern yourself with her. This is time for you to regain a sense of balance and calm in your life. You need this to figure out how you want to move forward with the rest of your life. You don't need to file for D right now. What you need right now is time to let things settle down. Detach, 180 and GAL.
