I'm having surgery and Dad's reaction to nursing home stay made me feel guilty. Any advice?

Hi Everyone, I want to thank you all for the helpful responses I see being posted here to the caregiving situations many of us face. I have a problem that has come up and would like some advice. I'm having total knee replacement in July and have made arrangements for my Dad (who lives with me and I'm caregiver) to be in a nursing home while I rehab. His stay will only be 10 days or so. When I told him this he was very upset/annoyed..wants to stay here with VNA homemakers and nurses coming in each day. Doesn't understand why I'm doing this and doesn't like the cost of it even though he can afford it. I might mention that my husband will be here and only wants to focus on me right now and not worry about my Dad. I feel guilty that I'm doing this even though I know I've do everything I can to give him the best care. He is newly diabetic and requires insulin shots, he's on warfarin for afib and has his INR tested and is 90% blind. His reaction was all about him and how he doesn't want to go and not my surgery. I've always been the "good, sweet" daughter who doesn't speak back or challenge..but this time I got firm and said he would have to deal with it; that this is how it has to be. I don't want to feel guilty..Any advice would be appreciated. Thanks!
