After meeting your parents. It was clear that they will never accept him. They were rude towards him and thought he is not worthy of you. You were now with him in the car as you both were going home. The whole ride was quite as he seemed mad.

One you reached home he opens the door for you and walked towards the house without saying anything to you. He wasn't mad at you but he didn't talk since he knows in anger he might end up saying something rude to you which he doesn't want.
