My (30f) boyfriend (28m) gets so toxic and competitive about games its ruining our relationship?

Pokemon card game which i loved, I dropped because he'd get so mad if I beat him. Same with yugioh, and magic the gathering. Even our previous flatmates were put off the game and wouldn't play solely due to how absolutely toxic he was when he was losing. We'd either let him win or just not play. Same happened with league of legends, any boardgames we play and now today even dnd, to the point I was crying because he was mad I as GM made a ruling he didn't like (it was the literal rule as read).

So, anyone with a partner, or themselves that has had this issue? Anger issues or such a blind sided competitive nature? Coz I need some help here.
