Was it rude of my fiance to tell me he rated me low in appearance?

My fiancé (28m) proposed to me (28f) a couple days ago. Yesterday he told me his bestfriend asked him what my score would be on the fashion and fire spectrum. Fashion means how well I would be considered a trophy wife/atttactive in appearance and style/able to be shown off. Fire means how good my character is. My boyfriend rated me an 80 to 20. He said I am a 20 in fashion (appearance) and an 80 in fire (character). I honestly felt hurt that he viewed me as low in appearance and that he was willing to tell me he saw me that way. Later he told me his bestfriend's opinion did not matter to him and he still chooses me, but I can't seem to shake off the hurt and disappointment. How can I go about expressing this to him? Am I being unreasonable?
