I (18F) and my mother (50F) haven't been on the best teams in the past few years. She's been neglectful and verbally abusive for years, iv been pushing myself away from her for a while now. But let's get into the resent events...

A little back story first, iv been with my bf (17M) for 2 and a half years and my mother has hated him ever since he called her out for letting a man that was creeping on me and my sisters live with us after I told her what he was doing. And my mother has hated my bfs mom ever since she found out she is a social worker. My mother has a thing against social workers, she thinks they just want to take kids out of homes instead of helping them. But anyway..

When I found out the date of prom I told my mom, she told me she would have to take off work and I would have to give her gas money, ok great! Sounds good to me... Until we get into an argument about something unrelated and she goes off about how I never appreciate her and I don't understand how much she sacrifices for me because she had to take off work and lose out on 75 dollars all to take me to a stupid prom with people she doesn't even like. And then I get reports from EVERY person in the house telling me that she said that same stuff to them on different occasions. So after I found that out I confronted her and told her she didn't have to take me, and I could easily get another ride because she obviously doesn't wanna take me, I told her she showed me how she really feels. She told me she didn't mean to it that way, but I'm not sure how else she would mean it and she didn't elaborate. We had another argument the next day about the way she expresses her emotions and anger (screaming, calling people names and throwing things) and she went down the "I guess I'm not allowed to have emotions" route, and also the "I'm sorry I can't give you everything you've ever wanted" page. And she said she's sorry she can't work 40 hours a week. (She works 15) I told her it was crazy that I work more then her as a 18 year old and that I just want her to be able to pay her bills. And I will not lie I said a lot of things to her, I called her delusional, mentally unstable and crazy. I bashed her dream job of being a life coach and told her she can't be a life coach if she doesn't have her life together herself, and I asked how she's gonna coach people when she's not over her past trauma either. She compared me to her father telling her she will never be anything. And she told me my bfs mom is brain washing me into thinking she was toxic and she called her a bunch of names. A lot of things were said but I told her that I don't appreciate her talking about my bfs mom like that and I told her she has no reason to dislike her because she hasn't spend more then 2 hours with her in the past 2 and a half years. And I told her I don't want her to come over to their house for prom because she doesn't know how to be civil and she's just gonna be fake the whole time or say something that's gonna make everyone uncomfortable like the last time she seen my bfs mom (she was only there for 1 minutes max and already made everyone uncomfortable) she left the house after that. she invited me to dinner after I got home from work the next day, I really didn't wanna go cuz I knew what would happen, but I went. She told me that the night before she thought about killing herself by jumping into the river. I said "doesn't that prove you are mentally unstable?" And she just got mad that I said that (fair tbh) but she told me she's gonna be heartbroken if I don't let her go because this is a big thing in my life and she compared it to me not inviting her to my wedding and said it's gonna make her look like a bad person (well... Maybe that says something?)

So ever since then she's been trying to argue with me about the stupidest thing imaginable, buying things at the thrift store, me putting MY Xbox in my room on MY tv and I bought (she thought I was gonna put it in the living room), how I can't do whatever I want just because I'm 18, and the stupidest argument of them all... My bfs facebook profile picture. (It's a picture of us both making a shocked face... Can you see where this is going?) When went on and on about how a pfp is someones first impression of you and "do you really wanna have that as your first impression?" And finally I got her to say what she really wanted to say... She screams "IT LOOKS LIKE YOUR ABOUT TO PUT A D*K IN YOUR MOUTH" followed by "and so does he" and "did you just get done or are you getting ready?" I told her that was a crazy thing to say and she's making it sexual for no reason, I told her she's been spending too much time with her bf (he's gross and makes everything sexual) she said adults just think about that if they see a girl with a their mouth open. (Huhh?) And I said next she's gonna be telling me not to drink out of a straw and she doesn't need to be talking when she posts pictures of her feet on Facebook and plenty of people like that, and also that normal people don't just think about that and she's probably just mad because she can't even have a normal text conversation with her bf because all he wants to do is sxt

So anyway, that's a lot to read but this has been my past 4 days and I'm exhausted. I don't want her there but I don't want her to hold it against me forever which I know she will, but if I do let her take me there and come with she will also hold it against me as a "sacrifice" she made and she will use it to tell me how ungrateful I am or use it has a wedge to get me to do something for her. But at the same time she's still my mom and I'm sure a normal parent would want to be a part of this but I genuinely don't know if she actually does, or if she just feels obligated or she just likes the idea of it, I'm really not sure.
