You and him were in an argument, not exactly an argument tbh.. you saw a girls text on his phone and you just asked him 'bout her like anyone Normally do, but he got a bit defensive which turned into an argument, when he suddenly raised his voice and shouted at you, which made you slightly flinch, as u look at him with a mixture of disbelief and upset, as you speak quietly..

You: "What are we..?"
