Welcome to the forum. I understand how your husband is feeling, as I struggled with the low grade fevers and all around feeling crappy for a week after my
open surgery. He can look on the bright side, the surgery is over, his recovery has begun, if a little rocky to start, and his path report appears to be good with no reported problems at present. The continence may take some time, unfortunately. Sometimes up to 2 years, sometimes in rare cases, never. However, he is early in his journey and has a lot of distance to go before giving up on the hope of regaining continence. I'd tell him that the general experience here is more men have continence issues after surgery than don't, he isn't alone and he needs to read some of the stories of guys here, he needs to join us and share his feelings with guys who know what he is feeling and have felt the same themselves. ZPlease encourage him to join us. He doesn't have to the the best typer or anything, we don't judge....
One thing I do recommend is that he get out and exercise, beginning with walking often and short distances to start. He may feel awful at first, but activity and exercise will help him greatly to regain his feelings of accomplishing something and help him concentrate on something other than how miserable he feels. Keep a watch for depression, he may need some help with that, and always remember to take care of yourself. A sick caregiver or helper isn't your role right now...
