Why is he doing that?

My boyfriend has voted on an Instagram story that he loves kfc more than McDonald’s and I love McDonald’s and I hate kfc then when I had asked him what does he love more he know that I love McDonald’s more he said that he love McDonald’s and hate kfc as I say so the question why does he copy me in things I love and why he said he hate that restaurant even if he likes it more?
