Aww Sonkie, can anyone at the hospital talk to you and let you know how he is, I know you don't want to keep on bothering them, but I'm sure they'll be able to let you know how he is.
It must be so difficult for him and there are bound to be times when he'll just turn into himself and not feel like chatting, completely understandable, but frustrating and worrying for you. keep sending him texts, let him know you're there when he needs you, you're a diamond sister to have.
