Glad you're going to a meeting, Crane.
He does NOT need you holding his hand in order to get sober. If it all depends on you and your "support" he is screwed before he even begins.
Let him have the dignity of doing this on his own without you. If you go back, you will probably find yourself "helpfully" telling him what to do and how to do it (we can hardly help it, ya know?).
Hope you feel a little stronger after the meeting.
