Sounds like you and your son have had a very nice, peaceful time while your h has been away. It will be interesting to see how he is once he's returned home. I'm sure he'll have a lot to tell you about his hunting adventure.
It's okay to hope, but keep your expectations very low or at zero.
I'm keeping you in my thoughts and prayers that maybe, just maybe, something clicked for him and he realized just how good he had it at home w/his family.
Enjoy your last night of peace and quiet.
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.
