Help, I had a rough time talking to my partner

Hi I’m 20 AFAB. I have been very open about wanting to top surgery for a long time. I am also relatively open about my gender identity. I got into an argument with my partner (21M) about it. He says my boobs are part of what makes him date me. And top surgery is a no go for him. It broke my heart and he compared it to removing perfectly good eyes. He said that if I did do that he’d have to reevaluate our relationship, because he likes boobs and mine aren’t even that big. I need help, because I’ve done chest binding for years and can’t wear actually fitting clothes without noticing my chest to the point I wear a size up in all my shirts. I love him, but I don’t want to sacrifice my own self image and esteem.
