SO thinks I'm making him sick on purpose

It's driving me crazy! My SO thinks because I undercooked hamburgers just once that I can not cook and that I'm making him sick. He doesn't cook or grill. That's all I do. Fucked up once and now he will say "I want spaghetti but I don't want it to make me sick" like wtf? Anyone else's SO do this? Or is mine just that big of a dick. Ugh it's so frustrating. I ask him what he wants and he tells me he doesn't know that if I'm hungry then go feed myself and not wait on him which I never do anyways!
