JanB - my warmest thoughts for your husband. I'm sorry to hear he has prostate cancer, but very grateful it was found!
There are many support groups for both men and their wives/husbands. It's nice to be around folks who know what you're both going through, also nice to be around folks who have so much information about the same situation. I've found cancer support groups to be very valuable, maybe you could try one or two and see if they are something you are interested in? (not that I'm pushing it, just that I "breathed a sigh of relief" when I found one)
Best wishes to both of you!
