Happy Xmas, you have come a long way in a short time.
Do that which you need to do for you. I am concerned if you pick up the burden of your H. As I recollect he has never been wayward, mainly unsupportive and wanting you to carry his load so he can play games as if a teenager. H seems from all you've said to live a quasi student life with similar friends.
Of course he misses you, his life was easy and infantile behaviour tolerated. H was waking up to reality without Di. It would be very easy for H to revert back to dependency.
Is that kind of R really enough for Di?
