PLEASE HELP!! am i allowed to not talk to him?

I am 17 years old. my moms bf and i kinda got into a fight idek, so this is what happened. I was olaying cod then he calls out for my sister and I asking us to chop the onions and cabbage so I went out while still playing cod on my phone, I already took out the soups that he asked for, but I couldnt leave the match cause my rank would go down, but just a little more time then the game wouldve ended. Anyways so he asked again while i was in the kitchen, I didnt do them right away I know but its cause of the game, I still tried to help out then he makes his way to the kitchen, kicks me out saying *sorry for interuppting your game* and thats when the game literally finished. I insisted on helping cause the game just finished then he rejects me saying *no your too busy go play ur game* Then i said but its fine, then i said *why are you like this!?* because he's just so dramatic like my mom usually comes home at 4:30 and it was only like 3:48 like did we really needed the onion that bad? then i got frustrated and cried in the bathroom quitely. I tried so hard not to cry but my eyes were ouffy when my mom got home asking me what was wrong which made me cry even more. Its not even just cause of the onions it just built up inside me because he critisizes everything. The time i get up, the time i go to bed, when i eat snacks at night, and not being able to use my headphones while doing dishes, also how I take protein powder, me weighing my food, me wanting to portion my food myself. Like it just built uo that i bursted crying. Then when my mom and i got to the dinner table he gets all upset cause he felt like he did something wrong, which he didnt I guess, it was myself who was just done I had to cry. He leaves the dinner table saying *enjoy your dinner* like sarcasm. Then later on when i was doing the dishes he then tells my mom what happened then saying *he was disrespected, and he wants consequences happening to me* My mom tells me to go apologize but I really don't want to, I dont even want to talk to him. I told my mom i want to minimize talking with him and she says I can't do that? I'm 17 still a teenager I just dont want to talk because him and I always clash, we just dont get along so I feel its best jsut not to talk other than greet each other is that okay?? Please help also do i really need to apologize??!
