For me, I'd also add that I would 1) go to a nearby hotel (which would kill him because it'd be wasting money), and 2) I would either call in sick to work the next day, or go in late, because I'm not going to worry about keeping up a good work record if HIS actions force my routines to be interrupted. This would also not be good for him or for our finances, of course--so maybe it would be a consequence that would hit him where he lives?
Is something like this a good thing, or a bad thing to do in trying to navigate a somewhat livable life with an ?
Well, boundaries are a very personal thing so what you find comfortable is all that really matters.
That said, I will offer that boundaries are NOT intended to be ultimatums or used as a punishment. It's about YOU creating a safe place FOR YOU during a situation you find intolerable. It's a way for you to defend yourself when you are feeling unsafe, disrespected, abused or taken advantage of.
IMHO your example above sounds more like a you are striving to punish him with consequences rather than acting in defense of your own best interests. If you find the situation intolerable & need to remove yourself, that's cool - but giving yourself permission ahead of time to skip work or create a financial strain because it will "hit him where it hurts" just sounds retaliatory to me.
