Why doesn't my husband like me?

In one of our numerous fights lately he commented on how I never want to look pretty for him. (as a side note our fights deal with some of my accusations of him cheating because other people came to tell me he was cheating but he still swears over our kid's lives he hasn't). That was like a punch to the stomach because I think I am pretty. Everyone tells me I am pretty. I have always had guys tell me my whole life I am hot/pretty/y. A few years ago (when I was age 18-25) I had two separate modeling contracts and did a couple jobs. I don't want to sound vain, but I never had a problem with how I looked. It is only since I met my husband that he tells me how disgusting and unattractive I am. I have straight, dark hair. He wants me to have curly blond hair. I have fair skin and have a hard time tanning no matter how hard I try. He wants me to be really tan. He makes it sound like all of our problems are because I wouldn't even try to give myself curly, blond hair and a dark tan. If I am comfortable with how I look then why can't he be. He wants me to be the complete opposite from what I am. And now my self-esteem is so shot I am starting to believe I am actually ugly and I am worthless. I am starting to feel uncomfortable around people in public too. It is so not me to think this way. But he has been telling me steadily for years now little things and recently he has been putting me down any chance he can get. This includes several hours worth of criticism in one day to where I have to leave or "fall asleep" to get him to shut up so I don't have to listen to it anymore. I have never ever crtiticised him about his looks or anything. He is definitely not perfect but I never saw any flaws because I love him so much. I never even had a thought to tell him something was wrong with him because I love him the way he is. I don't see any weight gain or loss, balding starting, wrinkles starting, etc. And I never make him feel uncomfortable how he looks. In fact I always tell him how handsome or y he is. I don't understand him.
