You’re so stupid

So today, I got up with my son, let my husband sleep. Whatever. When he eventuallly gets up, he is immediatly angry and goes “where is my phone charger”. I get up grab it and hand it to him. I ask “what’s wrong, why are you angry?”. In which he goes off about me touching his stuff. I’m mind blown. There is a charger literally in the bed right next to him. There is like 10 other chargers in the house. I don’t understand why he got so mad about this. I proceed to hand it to him and he goes “no, I want you to admit you were wrong”. I said “what? What do you want? An apology?” He said yes so I apologized then he proceeded with “that wasn’t a real apology. You don’t mean it. You were wrong!” I said “what do you want from me” then he proceeded with “ I want you to realize how FUCKING STUPID YOU ARE!” It immediatly brought me to tears, which he mocked me for. I dropped the charger to go to the bathroom….was it that serious?
