How was my day…

Idk why the guy who sa me my whole life is angry at me like so much anger when the only thing I did was stop the abuse and try my best to ignore him when I’m alone or not be touch by him. I don’t want want to make it obvious so I try to talk when my family having conversations but he make it big by “playing” telephone game. Yk where he completely ignores me and talk someone next to him and that someone say what he said. I’m tired of him acting like that. I should be the one breaking him down but it look like he’s the one who breaking me down. I feel sad and left out when he ignores me for some reason. I don’t want his weird attention but a brother bond why doesn’t he see that. I’m writing this because sometimes i have enough of him acting like a victim and no one doing anything. I’ll tell you guys what happened, he has four bird wandering around the kitchen and I don’t mind. I notice there’s poop stain on the floor so i basically said "oh look there’s poop" but it look like I was ignored (the ones who in my house is my abuser and sister). Later on I went down to the basement to get water seltzer from the fridge and I notice there’s no more so I decided to stock more . After that I took the cardboard that came from the drinks and head back upstairs. I see my dad came home and he’s in the kitchen doing his stuff. He ask me a question and I respond back so I didn’t focus where to walk and also cause why should I there shouldn’t be nothing on the floor and I forgot there’s poop on the floor but I thought my abuser pick it up that’s why I didn’t think much of it. I step on it by accident and realize when I felt something slide on the floor when I walk. I freak out but didn’t got mad just annoyed. He called me dramatic and stuff so I said as a joke "oh if it was (My sis dog name) yall would’ve got mad" and me and my sister giggle and even my dad more specifically bc I step on poop. My abuser as always being a "victim" started to get mad . At first I couldn’t hear well so I thought he was playing along like joking around (I hate to say it I still care about him as my brother). But I was wrong as him came closer to were I was he was mocking me and mimicking what I said like he was mad mad and he said "you know what nevermind " and I was trying to pass by infront him he secretly try to push me hard but since my sister there he only push me slightly. So I told my dad "you see, he the one who start and then get mad" and of course my dad didn’t say anything and so I look at my sister and she said "I’m not part of this" so of course I look like a fool and embarrassed. He literally a manipulator and also since he got "sad story" he deserves to get a pass just base on how my family deal with this situation. I’m just tired of it. Am I being dramatic and should just apologize to him and shut up?
