AITAH for saying this to my boyfriend

Last night my boyfriend and I were getting dinner ready and were laughing and having a good time, he was getting our plates ready and asked me how big of a piece of scallop potatoes and I said “not too big but not too small” and then I said “just like you” in a joking like tone. It wasn’t meant in a insulting way at all but my boyfriends mood totally shifted and as we sat down to eat I asked him what was wrong and he said that my comment was rude and he was pissed off about it. I apologized and told him I didn’t mean it as an insult if anything I was trying to say that he’s just right but also ssid I could see now why he may of taken it as a insult and that I really was sorry and it was never my intention to hurt his feelings and then went to give him a hug and he pulled away from me.

The rest of the night he sat on the couch basically glaring at me and then went to bed without even saying goodnight. I made him a “I’m sorry” card and put for him where hed see it when he got up for work, and he did cause it’s been moved but won’t even answer my texts now this morning. Am I the asshole for thinking that it isn’t even that bad of a comment?

Edit* – I thought I was saying hes the perfect size by saying this. I’m 30 and hes 35
