He chose his sister

My fiancé and I were playing a game with our friends and a question came up for my fiancé if he had to save either me or his sister, who would he choose. And he chose his sister.

Everyone started going “Ooooo” and knew it hurt my feelings. My fiancé looked at me and said “no no I would choose you”.

Honestly that hurt my feelings. I really believe he would choose his sister over me for most things. I know there would never be a scenario where he would have to save one of us , but I feel like he chooses her for a lot. Like when we go on vacation with his family, he will ditch me to hang out with her.

Do you guys think this is weird ??
