Unfortunately, you can't change or control her...but you can change/control how you interact w/her, as well as you react to what she says or does. Detaching will help with that.
As I've stated before in many postings, dig deeper for patience and keep the focus on you and your family. Find things to keep yourself busy and make sure your accounts are secure and safe, i.e., some of them tend to love spending their money as well as yours.
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.
