I swear to god, my dad is driving me insane

He gives me grief for spending so much time up in my room, but then when I do come downstairs and say hi he never seems interested in talking to me, and sometimes goes so far as to ignore me completely. I have no idea what he even wants from me! I wish I could move out.
