Am I wrong for cutting my mother out of my life?

I feel that my mom is abuser. She was for as long as I remember. She always made sure that her kids would feel worthless. To the point where she said to my brother - you will end up in jail, and to both of us - I don’t have children. Everyone else’s kids were angels. It got to the point where we just blocked her on social media. But not on phone since maybe there would be an emergency. She kept on sending aggressive messages once in a while so I blocked her number as well.

I love my grandma dearly because she played mothers’ role since we were babies. However, for the last few months she keeps on pushing my limits to bring my mother into my life because “she is so hurt and she need help for certain things”. I don’t want to hurt my grandma, but I don’t want to see or hear my mother. And it makes my grandma extremely upset.

Am I really wrong here?

P. S. mother found herself a boyfriend with 2 adult kids (about the same age as me and my brother) that she adores :). Whenever she asked my to help her with something, I declined and pointed to her “angel” kids in law.
