You really are going to have to determine many of these answers for yourself. There are no guarantees here, or anywhere else when mlc is involved.
You really can't know what stage she is in, or will be in next. She could bounce back and forth all over the place for quite a while. Her reasoning for this D is probably anything but reasonable, but you can't say that, and you probably can't reason with her at all.
All you can do is decide to take care of yourself. If you want to talk to her, I have no idea what you would say that would have a predictable respons or reaction. You know her best, or at least you used to. What ever you decide, we won't say you did wrong. At this point anything is a shot, but don't expect too much.
