Why Does My Boyfriend Invalidate My Intelligence?

Recently, my boyfriend and I were playing a game with his friends where we have to identify changes. They have played the game without me and both friends mentioned me being good at it and needing me to win the game. He gets a little upset by this and even brought it up to me that they said they suck when they play without me but that he feels like when I’m there, he finds most of the stuff. Which he does find some issues but I feel like he can’t handle the idea of me being good at solving issues. He’s done this on other occasions when we play trivia where if I solve something, he’ll say I didn’t. Or he’ll say I only got one right and ignore my contributions but accept his friend’s contributions even if I came up with the answer first. Why?
