pregnant & PISSED

My mother in law shows up to my house where I let her brothers stay free ( he came to work and make a meal for herself bc she doesn’t have a space to do it ) . They have so many animals and stink up the house . My partner doesn’t say anything. Well today after we left my partner said NO OME GO IN OUR ROOM she agreed . We even set up something so they wouldn’t come in . I came home after less than an hour and they put their cat in my room all the cat trees and a dirty ass cat LITTER . WTF IM FURIOS MY PARTNER REFUSES TO SAY ANYTHING . LIKE IS IT NOT COMMON SENSE TO RESPECT SOMEONES HOUSE ? OR EVEN ASK PERMISSION LIKE WTF IM LIVID .
