I know he doesn't want to have anything to do with her, but wow. He really ignore everything , like her words aren't even entering his ears, he isn't even looking at her and he really doesn't care about her even a bit. Even faces with her whatever feeling she had, his mind is filled only with "what a pain" kind of thoughts.
It is understandable stance, but ngl. If I'm in her shoes, it hurtful.
I think, his refusal confront her feeling and dismissing her whole being is just receipt for making bigger trouble.
