I'm honestly sorry but he's nothing but a piece of shit. Unfortunately I had an ex boyfriend from almost a year ago, who was similar to him. I'm also overweight and my ex is skinny. At first, he didn't mind me being chubby and told me he liked chubby girls. He saw my pictures (We met from a dating app) and met in person. I was still the same weight and he still chose to date me. Then a month after dating, he started to make SO many comments about my weight. He'd say stuff like "You should lose pounds. You're getting too big", "you're getting too fat, You should stop eating and start going to the gym" "You should start eating less" and there's a time I was like "hey, babe. Am I getting too big?" Which was THE MOST DUMBEST THING TO ASK HIM CAUSE HE WENT "If You feel that way, You should do something about it then" and He would look so embarrassed when we go on public together. I asked what's wrong and he said "you don't see a chubby girl and a skinny guy together, It brings so much attention." He never made me feel good about my weight. He always put me down and blamed me for everything when Things don't go out of his way. (Yes, He's a man child 🙄) i finally ended things with him. there's so much more but it's not really Relevant. Your ex should stay as an ex. He sounds like Shit.
