do men not like flat girls?

i mean i am flat and i have tried to gain weight but i cant and today he told me you are a door and i like him so much i mean he always has something to say about my physical appearance like, he would say things like ‘you dont have a body’ or ‘you are a door’ or gain some weight only then you will have a glow up. I am so tired of this shit. If he wasnt a good friend of mine i wouldve just stopped talking to him and idk whats wrong with me i am just too love struck on him that i accept what he has to say. So like guys dont really like flat girls?
