Deal breaker?

Been talking to this guy I like him he likes me! I HAVE NOTICED NOT ONCE BUT TWICE HE HAS SEEN ME EATING AND SAYS “don’t get fat” and it bothers me a lot. At first I laughed at it. Because of course I’m not going to get “fat” but then he said it again when I had 3 string cheese and a fruit up! I GOT VERY PISSED because 1. I HAVENT ATE ALL DAY! And 2. I’m kinda already struggling with my image after my baby and being 8 months post partum plus not at the weight where I want to be. I got upset and silent. But finally expressed it to him because he kept asking what is wrong! He did say “my bad” and are we cool I said yeah. But idk how I should feel????
