My significantly older bf of over a year always makes me feel guilty for eating.?

He has made weight comments before and he just makes me feel horrible. One thing he always says is, "Don't you want to be a hot little thang for your bf?" At the same time, he always tells me that I am beautiful. When we go out to eat, I feel like I am under a microscope and I could feel him staring in disgust. Why would he even take me out? I have confronted him about his rude comments, but still continues to dish 'em out. It's not like I am fat. I am 5'1" and wear a size 3. What should I do guys?
