Hi Hope,
There is another guy (40 year old), who just had a transplant a year ago. His name is Mark Yates and coincidently, he lives in Indiana too. Your husband might want to read his caring bridge page, Mark has such a positive attitude about EVERYTHING!

If your husband was running the business with you before, maybe can can start to pitch in again, little things perhaps. I think at this point (6 mo after transplant) it is detrimental for your relationship to look at him only as a patient, or for him to consider himself only that.
