Liz,
There is not much I can say that hasn't already been said so eloquently by others... I was so sad when I read your post, I was thinking about what a tough time you and Rob have had, and now this... I wonder if part of the reason he had such a hard time dealing with everything was that he feared this end result, but now that it's a reality his true self is shining through. You are both in my thoughts and prayers.
