Patience, Morgan. It takes a little time. He can't just say "never mind" and come home. He needs to work it through, and maybe convince himself that this was all necessary to get where you are now.
If it will help you, practice pushing your own buttons. Write down every thing you think he might say to you tomorrow. Then think of the perfect DB response, and write that down next to it. Then read them out loud in front of the mirror. Laugh yourself silly trying to make his "mad face" in the mirror while you say his lines.
Careful though, we don't want you laughing in his face when he says this stuff tomorrow.
