Hi yes I think the card and gift certificate would be very appropriate. I know that bdays and xmas were a nightmare as I wanted to give something but didn't know what was appropriate.
My H was also off sick during most of our separation. He did in fact receive medical retirement and that was a year ago now.
You have a good positive attitude and I am sure he sees this and judging by the amount of contact you have you appear to be helping anchor him slightly. Good luck and keep doing what you are doing as it seems to be working.
