Everything that you posted is very, very common w/the MLCer. She may be starting to question her life and looking at where she's been and where she's at today and starting to think about her future and what she thinks she missed along the way. She hasn't ramped up into full blown replay just yet from what you posted.
Sounds like you aren't putting any pressure on her, which is good. The more you talk about the relationship and put pressure on her to change back to her old self, the more she will go into a rebelling state. Right now, you are accepting her for the way she is and not acting like an authority figure to her child/teenage self.
Try to keep the focus on you and your children. Watch your finances. Continue to do things for yourself in the way of GALing.
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.
