He drives fast when we argue ..

My boyfriend and I were arguing in the car over something SO stupid. The radio was on and he kept repeating the word “Smokey” because it popped up in a little commercial. He repeated the word a good 4 times before I said ok enough it’s annoying. He speeds up on the street fast enough where he slows down to get the red light and my seat belt locks. We continue driving really fast and pull into a gas station and he turned so fast my seat belt locked. I told him it isn’t safe the way he drives when he’s upset and he said “it’s not safe the way you talk to me”..... because I called him annoying? My words won’t kill you in the car but your driving could injure you, me, our baby that’s growing in me, someone on the street...
