Asking him to call first is a reasonable boundary, but that doesn't mean you need to set it. For now, maybe not, as long as you can handle the consequences! I wasn't sure you were last night. But, at least in the short term, setting that boundary would make him angry, or should we say angier. I you can figure out how you can deal with it, I'd leave things as they are. Tomorrow, well, it could be different.
