AITA for refusing to salvage my relationship with my mother?

My mother 40F has recently been trying to pressure me 18M into spending time with her. I know this already makes me seem like an asshole who doesn’t want to hang out with his mom, but I want to give some context.

A little less than a month ago, my mother had a mental health episode. She’s had multiple in the past few years; to varying degrees of severity, but this one was her worst. She ended up attacking my sister and my father; and when I attempted to step in, she attacked me.

I’ll admit that I fought back; I ended up kicking her in the stomach before locking myself in the bathroom and calling 911. Some stuff happened with the cops, don’t really know what cause I’m really educated about the law, but she was hospitalized for 24 hours and put through a psych evaluation and now has three charges of second degree assault.

(The state filed those, not me)

They basically just said she has anxiety which I don’t think is accurate because when she attacked us she was basically screaming bloody murder and making zero sense. She very clearly has something going on; and there’s no way that it’s just anxiety. But all that to say, this was kind of my final straw.

I know she’s mentally ill, that she has her stuff going on and this isn’t her, but she’s done nothing but be horrible to me for the past three years and I’m just at my limit. I’m not speaking to her, I’ve been eating alone in my room; whenever my dad is working and I spend the day at a friend’s house. She’s basically just a roommate now.

All of this background to say that tonight when I went to make myself food she basically ambushed me and told me she wanted to have a family therapy session. We’d had one a week before and it went about as well as expected— so hearing that she wanted another one I just kinda laughed. I’d made it very clear multiple times that I’m not interested in trying to salvage a relationship and am cutting her off as soon as I’m legally able to leave.

But she persisted and told me that she wanted to talk about what happened and “have family time” that she had “planned a vacation”, I just told her that I’m not interested and went back upstairs but now she’s texting me about going to the movies together??

I don’t know, I need advice; how do I make it clear to her that I’m not bending on this issue?

Edit;

a lot of comments have been asking about my dad and his role in the situation. He’s been very supportive and has been doing his best to be there for me. Hes pretty worried about my mental health, hes checking in on me a lot.

My dad has made it very clear that I had every right to call the cops and that he’s not mad at me for doing so, but he’s also expressed how that charges could be making my mothers mental stuff worse.

I honestly didn’t think when I called the cops. My mom had broken my finger when she attacked me and I thought she might’ve broken my arm; so all I could think was “what did she do to my sister”.

Anyways. Some people have asked why my dad hasn’t left her; he has a lot of trauma with my grandma and her bipolar disorder. My grandma based away very suddenly and very intensely and I think my dad is worried that if he leaves my mother; something like that could happen again. Also leaving your spouse is no little thing, especially when we aren’t a very wealthy family.

Other people asked why he hasn’t stepped in to protect us; he definitely has. During the actual attack, he tried to yell at me to go back to my room so my mother wouldn’t attack me; he also physically put himself between my mother and my sister. He was usually the mediator when me and my mother fought, and made sure to call me after every time my mom had a mental episode. He does as much as he can— but he works a lot so he’s not always there.

People have also asked why I can’t move out if I’m eighteen; I’m just gonna answer that here cause I’m sortve tired of answering the same question again and again. I’m not legally recognized as an adult where I live until I’m 19. I do have a job and am saving up for an apartment, in hopes to get out as soon as possible.
