Get it through your head that no matter how much you dislike, or even hate me, I’ll put up with you for Harry’s sake. What you will not do is belittle him for how he copes with his trauma. He is allowed to be hurt and upset because of everything that he’s been put through. Trauma is a normal response to all of the hell that he’s endured, he is not seeking attention. If he doesn’t want to speak, let him communicate in other ways. Learn the spells. I’ve taught Luna, Weaslette, Pansy, Blaise, and Neville.
