If you are not being given information about his plans (which you are not, at least in this case), you get to make your own. Do it b/c you have the right to make plans (as opposed to punishing H) and both you and your S get to enjoy life. Not wait around for his sorry a$$.
You can have compassion for your H as far as him being in a "bad place" right now, but that doesn't mean he gets to treat you badly. When he does, excuse yourself and let him know you won't talk with him (let alone agrue) when he's yelling. He's a big boy, he can control it if he chooses.
