She could be in a number of stages, anger, replay, depression and withdrawal. Keep in mind, that the stages are not linear. They bounce back and forth for a very long time. I venture to say that she has some anger as well as being in replay. Depression is the main ingredient of MLC and that will be there throughout the crisis. There will come a time when the deep, dark depression hits and that is when withdrawal is more evident.
Right now...focus on you and leave her to crisis. The crisis will take as long as it takes and she's the only one that will determine the length of time it takes.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
