She's not ready to read those chapters or anything else that may be relationship information. She probably doesn't want you trying to tell her about what she's doing. Many of them do not like for us to tell them what is wrong with them and how they can make their lives better. Leave the relationship books in the drawer for now because she's not open for that kind of learning at the moment.
Keep the focus on you and your family. Let go, let God have her for a while. You cannot fix her for you didn't break her. She is the only one that can fix herself.
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.
