So sorry for what you are going through. I fear that I will have to become so dependent on my hubby. But he loves me as much as you love your hubby. You are both lucky that way. Thank goodness he does have you to depend on. You are wonderful with him and for him.
Now, my concern is for you to also take care of YOU. Be nice to yourself every chance you get. He wants it that way for you. you are in my thoughts and prayers!
