You need to take care of yourself before us, the readers. Real life happens.

There's probably things happening below the surface that you aren't aware of in your Dad's half of the family. If you don't have rides then how are you suppose to be where you can't. The fact that he's having difficulty remembering things could be stress or something medical. Apologize for the inconvenience of you're not being where he wants you to be and tell him if he needs you to move out then you'll make the arrangements. Something along those lines anyway. Be mature about it. He's overreacting for some reason, give him a graceful way to back down.
