Boobs and my boyfriend

So my bf knows I have small boobs and I thought he was ok with them and he said he liked them and I've always liked my boobs so I was happy that he was happy with them but now he's like well maybe they'll grow more soon and oh if you eat certain foods they grow more and now I'm like I'm sorry I'm not changing for you I feel like if he's super upset about my small boob and wants me to change my body then clearly he doesn't love me for me like he's always made clear to me
