You love him, I get it.
One question: how much do you love yourself? What are you giving up of yourself to coddle him? I quote: "For right now, it's all about him and getting him feeling 100% again." What if that takes 20 years? What if it's never? So you are willing to give up everything - hopes, dreams, fun, friends, career -everything for someone who is white-knuckling his alleged recovery? Obviously you have that choice and that right, but I wonder why you don't care a little about yourself?
