Saying a prayer for him Cnder.
I know how difficult it can be for him and for you and Bill as well.
My baby (well she's 23) moved out a year ago and not a day goes by that I don't miss her terribly! It does get better as time goes on but oh how they are missed!
I'm sure he will do just fine after he adjusts and so will you.
I will keep you in my thoughts and prayers.
Hugs ,Kdee
