Has he chosen his dialysis method (peritoneal or hemo) and if hemo, his access? At least you have a few months rather than having your husband wake up in the ER with a chest cath, so there is a small bright side, but I understand what an overwhelming time this is. Most people seem to say that the waiting is harder than the starting, so now that you have your date, you can stop wondering 'if' or 'when' and start preparing yourselves.
Will he try for a transplant? He can start the process of getting on the list now.
I think Vera had great advice - use this time to read and learn about your options. Has he applied for Medicare? Do you have private insurance? Dialysis and transplant are treated uniquely by both Medicare and insurance, so best to get in touch with a dialysis social worker (through your unit).
Oh, and a big
to both of you!
