Lack of affection

I've had back cancer for about a year now. I got married in April and just recently the back pain is tremendous to the point where I wake up multiple times throughout the night and not even scalding hot showers work anymore. Last night I accidently woke my husband up because the pain was unbearable and I kept having to get up. He woke up and was basically be unsympathetic and claiming that he was irratible because he was too tired to be up. I get that it was the middle of the night but I was in so much pain and even told him I didn't need anything. Today when he got home he brought me some heating pads and chai tea and laid down with me for about five seconds and started feeling me up and got horny. I told him I physically couldn't do that right now so he said he was going to take care of it himself. I was fine with that until he said hey you don't mind if I watch some porn while I do it do you....... I'm in pain on the bed barely able to get up and feeling immensly unattractive and he asks me that? Usually I wouldn't mind but instead of comforting me he wants to jack off to other girls. I just want someone to hold me and tell me the cliche everything is going to be okay I love and I'm here for you. I feel unloved unsupported and unattractive. I need encouragement right now.
