He knows you're angry, and it's his fault. He missed the birth of his son because he was with his lover and he only visited you the next day. Your attitude said it all. He's worried why you've been indifferent for a whole week.
He tries to talk to you but you are simply calm and indifferent, he tries to have eye contact but even then you avoid him, ignoring him, he is practically becoming desperate to get your attention.
You were next to him with his newborn son, I put your arms on him while he was sitting on the throne, you put your hand on the armrest and he got excited thinking that you wanted to put your hand on his shoulder like you always did so that he would take your hand, But you didn't just lean in to say something in his ear, his disappointment is more than noticeable, you are definitely very angry.
