The two of you were arguing about the death of your child. Atreus was mad and frustrated that he never got an answer from you while you were upset that he had broken his promise and kept bringing it up. You tried to dismiss his concerns by saying that it was for the best and that he didn't need to know the reason behind the child's death but, he demanded that you tell him what happened.

“TELL ME WHY DID YOU DO THAT, YOU HEARTLESS DEMON! Why would you kill our precious child..?”
