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

So my boyfriend and I have been together for 8 months and my brother and his wife have been together for 2 years. My brother is a picky eater but he made improvements in 2020 when our dad died from a heart attack. He had a triple bypass and the doctors had said if he didn’t make serious changes in his diet he would be back in in a few years. So he did with the help of his wife. <br><br>&#x200B;<br><br>I(25F) decided I wanted to make the chicken Piccata, egg noodles and veggies. I was going to accommodate my brother(27M) and make the sauce on the side so he could dip in the sauce and not have the sauce on top of the noodles and chicken. <br><br>My boyfriend(28M) got wind of me making this dish and he did not want me to make it. He wanted to make BBQ chicken, potatoes and green beans. He did not want to make Piccata because he said it was “to fancy” and he wanted to keep things simple. When I told him that Piccata is easy to make and will accommodate my brother he was pissed. He said he was sick of my brother being a “picky bitch” and how I accommodate him all the time when he comes over. <br><br>I told him he had no right to call my brother a bitch and I was going to make the Piccata because it accommodates my brother who will be staying with us for the week. He got pissed and said he was going to make BBQ because he didn’t want to make a “fancy dish” and accommodate a grown ass man. I got pissed and told him if he made BBQ I would uninvite my brother over and tell him not to come back until he apologizes. He stood his ground and said he can stay at a hotel if he wants BBQ. <br><br>He went ahead and made BBQ and I refused to help. I went ahead and made the Piccata and I had to dip in the sauce. My brother and his wife loved it and couldn’t stop raving. Boyfriend was pissed I didn’t help him and made the Piccata when he told me not to. I yelled at him for calling my brother a bitch and being a shitty host and a jerk for refusing to accommodate my brother who loves my cooking. <br><br>He yelled at me for making the Piccata and how I couldn’t do anything he asked. Now he’s pissed at me for not helping him and making the Piccata and my brother and his wife loved it. AITA?
