GG, Your h honestly is a confused mess right now. One minute they want a divorce, the next minute they are talking about the relationship. You can't analyze anything that they say or do right now because they are operating on emotions...nothing more. Their emotions are running extremely high and rational thinking is out the window.
Sit quietly and patiently. You'll learn more by doing so and yes, information that you are seeking will fall into you lap quicker this way. Allow the man upstairs the time to work on your h. Give him the entire mess and keep the focus on you and your family. I know it's difficult, but you didn't break him, therefore, you can't fix him.
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.
