My boyfriend’s older sister’s birthday is today and I didn’t go. This morning his sister let me know (my boyfriends owns the house, his sister rents from him) that she planned on going to an arcade/bar type of place and I said I might go. 
I consider myself introverted and all day I was pretty much psyching myself up to go to this dark bar for a couple hours, play a couple games, and most likely sit and watch my boyfriend and his sister play against their younger brothers. Instead, 30 minutes before we were supposed to go, she texts us that the bar is closed on mondays and they’re heading to a restaurant instead.
I immediately said no. I was not expecting to have to sit down with people in a loud, bright restaurant with food I cannot eat because everything on the menu contains either cheese or meat. Not only that but the last time I went out to a birthday dinner with his family (boyfriends birthday), I spent the whole 4 hours being ignored. And when I say ignored I mean they specifically direct their conversations at certain people and the only person who spoke to me was their mother, who is not there tonight.
So AITA? I know sometimes I can be dramatic but I feel my reasoning is pretty solid. When my boyfriend called his sister to tell her his order because he was late she didn’t ask for mine either so I feel like I wasn’t expected to come anyways
