Wishing, What does the coach think you can do about reinforcing his policies w/your h? Your h is a grown man, even though he's acting like a teenager. He's going to do whatever he wants and think whatever he wants and yes, he may appear to be on the same page, but that was then and today he may change his mind. You have no control over your h and trying to reinforce something w/him is just going to aggravate him. I'd leave it alone unless he raises the subject w/you.
His priorities are all about him and what he wants/needs at any given time. The song he's singing is called "me, me, me".
Keep the focus on you and your children.
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.
