WR, Hopefully you slept well last night. I'm happy to see that your h texted you back. He will be well taken care of and there is no need to sit and worry about him today. If he needs you, he will contact you or your sons.
As for your son not receiving any information for 22 hours, that may have been the wishes of your h, not his aunt. Your h may have wanted to wait until he was out of surgery before his son was told. Maybe he didn't want he family coming to the hospital and worrying about him, who knows what goes on in their crazy little minds. But, at least your son was told after the fact and that's important because his father could have chosen not to tell him at all.
Try to enjoy your day and allow God to work on your h.
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.
