Helicopter mom

My mom (Drunk) is trying to force me to drive out to a guy’s house who’s throwing a party my brother is at because she wants him home. He’s 21 years old. She threatened to call the cops because she believes they’re “holding him hostage” along with “having his phone” and “forcing him to stay there”. What could they do? She’d be wasting their time because she has no idea where he lives, and they’re all of age. My brother told her where he was and she flipped out. He’s now ignoring her calls and messages because she wouldn’t stop spamming him. I honestly don’t blame him, and have done the same thing. She gets overly possessive and starts blowing up your phone if you don’t answer within 10 seconds. Shes never lets us go out and spend time with anyone. She’s been possessive of us our entire lives, and we’ve missed out on so many things because of it. Anyway I personally know the guy. I grew up with him, and he was my best friends at one point. I talked to him 5 minutes ago and he sent a photo of my brother hanging out. He said he was too drunk to drive anyone home, and he offered to let my brother stay the night. My mom of course is freaking the hell out and assuming there’s underage people and drugs. There’s none of that going on. Chill the fuck out and leave him alone. He’s a grown fucking adult who’s allowed to make his own choices. I’m having to lie to my mom and tell her I don’t know the guys last name because she’ll spam message/call the guy to make him tell her where he lives so she can go get my brother. She thinks I know where he lives, and I 100% don’t. Of course she thinks I’m lying.

So glad I’m moving out and away from this place. Even then, she tells me I’m not allowed to get a job once I’m moved out, and she’ll be paying my half of the rent. She told my boyfriend that too. I can’t trust her. I know for a fact she will hold rent against me if I don’t do what she asks. I can’t and will not give her that power. She can decide she doesn’t want to pay my half of the rent, and make my boyfriend pay it all because she knows he has money. I will not let her abuse him like that. If I have to get a job (and I will be) behind her back to save up money incase that happens, then that’s what’s going to happen. I want her to have NO control in my life. I’m tired of it. She’s beyond possessive and I want to get away from that.
