LT, Your wife is slowly waking up and she feels safe to talk about things to you. I would be a friend and just listen and validate. If she asks for your comment, then you provide it...otherwise, just listen. The more you listen, the more you will learn about where your wife's head is at right now.
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.
