The little problem?

Hey guys! It's been awhile since I wrote on here. Well this weekend I was at my sisters house spending the night and getting away from my house. I got a random text from my boyfriend on Saturday about my brother. My boyfriend found out that he broke up with his girlfriend and he wanted to know on what happened. He just wanted to be there for him. Instead my brother went off on him and started to cuss at him through text. Then he brung me up and started to ask him on why I've been avoiding him. I wasn't, I am just stuck at the house. Taking care of my mom's kids and cleaning her house. I am going to go get a job and I can't leave the house unless I catch up on every single class and homework. My mom is home sometimes. She yells at me to go get a job and to focus on school while taking care of her badass children. They don't listen. Not even to her. She lets them run her over. I'm sick and tired of it. I wanna move out rn but I can't. I don't want to leave my little sister there with them. Me and her are the only ones who actually clean that house. When we leave its nasty and all disgusting. If so then why don' you guys clean up? Hmm? That sounds like a great idea. yet nobody considers it. Anyways back to the story, my brother was telling my boyfriend to leave me. Are you serious? Then he tells him that I can find someone even better and that I don't need to be wasting any time on him. Then tells my boyfriend that I am going to leave him. When did I say that? I said I wanted to talk to him but not as "I'm going to break up with you" way. Like I just wanted to know what was going on since I don't get to go out. Like everyone else does but I can't. I know he was probably being protective but that was a rude way to be protective. I don't even know why he did that in the first place. If I could upload pictures I would so you guys can see the screen shots. So could you guys help me with this situation? Like how should I respond to it? My brother hasn't spoken to me. What would you guys do in this situation?
