I'm going to make this as nice as I possibly can 😂

So my boyfriend is the most amazing man I've ever met. We eat with his parents every Sunday (they are really nice people). But I sit across from his dad and they are southern so they eat fried foods and I'm not going to lie, the food is amazing. But, they are a bit larger than I am and they eat more. I only get one scoop of everything (which is plenty, she makes a lot of sides) and a piece of chicken or steak or whatever she has. And his dad looks at me while eat and he looks disgusted!!! It makes me so uncomfortable. I take small bites and I don't smack or make noises when I eat so why does he do that?? And they made ribs one time and I only had 2 (they were huge lol) and he made comments like (when I die I don't want you to cut me open and do my autopsy" I want to be a medical examiner. Lol. Idk it just bothers me, he always makes comments and watches me eat and it gets uncomfortable.
