Moving out at 18😰

So I just turned 18 recently. My parents and I have never really had the best relationship because my mother is mentally, physically, and verbally abusive and he refuses to do anything. I decided I wanted to become financially stable and live with someone else. My bf of 2 years suggested I moved out with him. I have borderline personality disorder, and my mom uses it against me whenever possible. Everyone in my house believes she’s bipolar. And my dad is a pathological liar. My family is strict but no. I CAN go out, but I can’t do drugs. They are very controlling. I can only hangout with people they like, and make me cut people off and blame everything on me

Problem: so today I was getting ready for work and my dad called me downstairs to tell me I’m a liar. When I asked why he said he found out that I had gotten 2 piercings. (In which I did so I said yes) he told me to pack my things and get out. I wanted to wait for my mom to get home because she owes me $500 that she stole out of my account when she had control of it. She came home, and my dad texted her about it so she called me a slut and said that if it was the 80’s I’d be the biggest tramp in town. So I decided to pack my things and reserve my flight bc my bf just moved to FL.

Idk if I’m making the right choice. All my friends say yes, because they’ve saw her get physical... but I’m young. He said his mom will take care of me like one of her own daughters
