Just one other thought.
You keep talking about how hellish the worrying will be once he is out--that you won't sleep, that you will be suffering constantly.
May I suggest that you open your mind to the POSSIBILITY that you may learn to let go of your worries, that you may be able to live in peace even if he chooses not to? A lot of us thought we couldn't STAND being apart from our loved one--but gradually learned to appreciate the peace from not being in the middle of chaos every waking minute of the day. We gradually learned to take care of ourselves, regardless what our loved ones were doing.
If you consign yourself to a life of worry, fear, and suffering before he's even out the door, that's what you are likely to get. Keep moving forward with your own recovery.
