Is my step dad emotionally abusive?

Bri

Well ill go back to the first time he called me a pig. Im not fat but I’m not skinny either. Anyways i burnt my hand on a bowl of ramen and i dropped it in the sink and he came in there and called me a pig and i told him im not a pig just because I dropped something and he said yes you are. I cried. He also sometimes calls me a pig if my room is dirty. One time i had a friend over and he came in my clean room and says welcome to the pig sti. Then i was drinking a can a dr pepper and he had the nerve to say drink another one of those you’ll just gain another 100 pounds. I stayed quiet. I feel like I can’t say anything or I will get in trouble for talking back. I told my mom about it and she hasn’t done anything. I’m scared to eat in front of him cause I don’t want him to call me a pig again. It really hurts my feelings. If i say something to him either I will get in trouble or he will call me a sissy..
