So every year my family goes on a beach trip down to Florida. My boyfriend (24 M) and I (24 F) are always invited and we go. My parents pay for one big condo for the whole family to stay in. This year my mom asked if I would share a room with my sister (20yf) because she doesn’t like my brothers girlfriend, and she can only find 3 bedroom condos. My brother and his girlfriend are 19 years old. Initially I agreed but the more I’ve thought about it, it is really starting to irritate me that just because of my sister, my boyfriend of 3 years, who I live with, and I will have to room with her while my younger brother and his newer girlfriend get their own room. I’ve thought about us getting our own condo in the same building but they only have 2 bedrooms, which would be a waste of money for just the 2 of us. But I also know if we were to find a 1 bedroom and stay somewhere else my mom would be upset. Everytime I try to bring it up with my mom she just instantly gets upset and tells me she didn’t think it would be a big deal and we can’t have a conversation about it. Which it isn’t the end of the world, but being older, and in a very serious relationship, it feels unfair. I feel stuck because since I’m not paying, I don’t feel like I have the right to say “im not doing that” but at the same time if we were to get a condo someplace else, i know she’d also be mad. AITAH?
