keep strong. The story you posted is eerily familiar. My AW is not as bad. But the story is the same. She will say and do anything to get me past the moment I file and get me to change my mind. I suspect yours will try to. Keep her behavior in mind, and remember past performance is the best indicator of future behavior. You know it. You've seen it. I'm not saying anything new.
Best to you. I wish you well on the first day of your new life.
