Renee, There is a book called "The Script" that may help you better understand some of the behavior that your xh has and is exhibiting towards you and the family. It was written by Elizabeth Landers and Vicky Mainzer.
No matter what happens, you and are going to be okay. You can only control what is within your grasp and nothing more. Turn it all over to God and allow him to do his work.
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.
