Take each day as it comes, sit quietly and the answers will be revealed to you.
If the old h is returning, it will take some time for him to feel comfortable in his skin once again. Both of you have changed so much during this journey and the both of you will be starting over again, hopefully, as friends. Take things slowly and do not rush the process and definitely leave the ow out of the mix...there will be time enough to share your thoughts/feelings, etc. w/him once he's fully awake and strong enough to listen and actually hear what you have to say.
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.
