AITA for calling my boyfriend a jerk for refusing to accommodate my brothers eating habits?

So my boyfriend and I have been dating for 11 months. In fact our 1 year anniversary would be this coming Sunday. So my boyfriend thought it would be a cool idea for him to cook for my parents. He wants to make fish tacos. <br><br>The thing is my brother would have to come as well because my parents don’t like leaving him home alone. And my brother has very particular food habits. He is an extremely picky eater. And he will only eat what he likes. Which isn’t a lot. I told my boyfriend he would have to make some chicken strips on the side and he said no. He said he won’t accommodate for my brother. <br><br>I think this is a little ah considering it’s for our anniversary and it’s not like he’s making a five course meal for them. He can easily make some chicken strips along with the fish. Also what if they don’t like the fish? He could also make some chicken strips. I told him this and he said he will do it how he wants to since he’s going through the effort of cooking. <br><br>He did say he will make sure there is soda, juice and milk for my brother to drink. He also let me choose the flavor of the cake so vanilla. Which is my brother’s favorite. So I feel like I might be an asshole for being upset that he won’t make the chicken strips.<br><br>Edit: I also forgot to mention my brother is 24. Not a minor.<br><br>Also the reason my parents don’t like leaving him home alone is because he is very destructive when they aren’t there.
