NP changing plans from hangout to hosting day of

My NP and I live in a small house and have an agreement to give the other person a 48 hr. notice if you want to host at the house. That's usually enough time to make some plans. Any other time a meta is over isn't considered a date and it's not assumed you'll have alone time (though I usually keep to myself with some headphones or find some plans anyway).

NP and Meta work together, while I work from home. NP asked on Monday if I would mind Meta coming over after work tomorrow (Tuesday) for a couple hours. I agreed but shared that I would be at the house and in an *important work meeting* during that time. Tuesday rolls around and I get a text from my NP asking to have the house during the *important work meeting* in order to host a date with Meta. I said no but I'm feeling a little bothered by it because we just talked about this the night before.

For those of you who live with a partner - am I out of pocket for being annoyed? Is this something you'd talk to your NP about or is it more of a "wait and see" thing?
