Feeling upset?

I texted my boyfriend and said "I want some hot wings" so he says "eat a salad"... So then he says, "you need to start eating healthy, I'm not saying you're fat but you need to start eating better because you eat bad and I care about you" but that's like saying "you think I'm getting bigger?" He knows, I'm lucky if I eat anything at all through a day. & usually I do eat a salad. He might hear me say "I'm getting a gyro, or polish" but that's it, and that's if I eat... Sometimes I go days without eating.. I don't know how to feel about that? I already feel insecure and that just really made me upset.. Then he tells me "look up some workouts....
