u/M-Jdoane

I (18F) am a high school Senior living at home with my Dad (46M) and my little brother (14M). My Mom (45F) and Dad recently got divorced and my Mom isn't living with us anymore.

For context, my Mom has bipolar, schizophrenia, BPD, and NPD while I have Autism. Growing up, she was emotionally and verbally abusive towards me. My parents would go through this constant cycle of abuse where they get into a fight, they don't talk, my Dad is forced to apologize, and everything is peaches and cream.

She was also abusive towards my Dad, emotionally, verbally, physically (on certain occasions), financially, and (possibly) sexually. She once threw a bowl at my Dad which snowballed into a CPS case where me and my little brother were almost taken away. And my Dad once told me that he'd sometimes wake up to find her naked and on top of him.

She has two other kids from a previous marriage (26M and 22F) that she royally fucked up thanks to her abuse. She didn't bother to get therapy or take medication during either marriage. It wasn't until she divorced my Dad that she started taking medication and going to therapy.

My Dad and little brother say that she feels sorry for what she has done and wants to go to my high school graduation. With my Dad saying that he knows I have enough empathy to forgive and let her attend since she's my Mom. And that she'll cry if I don't invite her.

When my half-sister graduated, she didn't invite my Mom. My half-brother has severe autism and therefore didn't graduate or attend high school. And my little brother is only 14, he isn't in high school yet.

I feel conflicted, on one hand I feel like I have to invite her because of family pressure. But on the other hand, I don't want to because she has deeply hurt me in ways that have caused irreversible damage. So, WIBTA?
