Okay so I need some advice here. So my boyfriend told me last week (told, didnt ask if it's okay) that his sister, her partner and her two young children (have met the sister once two years ago) were going to be staying at our house on the 23rd of December and that either I should go stay at my mums/sisters house for the night or that we would sleep in the lounge so his sister and partner can have our bed. I know this might come across as being mean cause you know like I get the whole family first thing but I'm literally so upset and pissed off! Our house is tiny! Like I don't even want to be here if theirs going to be four other people staying. I also work in retail full time (Tues through to Sat) and I was really looking forward to just relaxing at home the weekend before Christmas. Plus, my cat is semi sick and has never been around kids before so I know he's going to get pretty stressy but I feel so bad leaving him to stay at my mums for the night (my cat is my life) Like I dont even understand where the kids are going to sleep seeing as we only have one couch, AND we dont have any spear blankets or pillows??? I feel like he just agreed to let his sister and family stay without thinking through everything that needs to be done and prepared, and he didnt take my feelings into consideration and how its TWO DAYS BEFORE CHRISTMAS!! Like to be fair I probs wouldn't mind if he had of actually asked me and if it wasnt right before christmas day. Guys help me out here, am I being a bitch? Or do i have the right to be hella annoyed right now cos i so want to talk to him about this.

Edit: I talked to him about it and he said I'm being selfish and only think about myself 😶😶😶😶
