Don't worry, I would never let him drag me down. I kvetch here about the things that bother me but most of our time together is actually quite good, and I'm trying to avoid the possibility of him being in a situation to die alone - a distinct possibility if I were to just walk. But if he can't get any better at some of the things he needs to work on, that may be the ultimate outcome. And if he continues to improve clinically (doubtful but possible) then he could be in a better position to be on his own.
