Scooby, Keep the focus on you and your children. You will find that thinking about your h and what he's doing will consume you and your day and leave little time for pleasant activities. I know you are concerned about him and his actions, but no one knows what he's going to do or say and guess what...neither does he at any given minute. Emotions run high for him and let's face it, people who are running on pure emotions doesn't think logically.
Enjoy your day w/your kids.
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.
