AITAH For Continuing to See My Boyfriend After My Parents Forbade Me Not to?

(Burner account)

I (18F) have been fighting with my parenst (43F &41M)(not religous) for 3 months now over me continuing to see a boy(18M) that I've been with for 9 months now. For context, my parents have NEVER held a conversation with my boyfriend. They are just quick to assume. They also dont like that my boyfriend is not an honors kid. Thats why when they found out that my boyfriend and i decided to take things to the next level and they lost their shit over it. When confronted, I denied but came clean once he admited to everything. His family is chill with us continuing to see each other (for the most part) but my family hates him. Since im going 400 miles away for school in the fall, we've been trying to maximize our time together.

We are both going to school in the fall. He is staying close to home while I go away. He is paying for his schooling, I am not. My grandfather(very religious like my grandmother) is paying for it. My dad keeps threatening to take away my college if i continue to see my boyfriend and last night is when the dam broke again.

I went to a festival that was beside where i work to go see my boyfriend. We went and hung out for about 3-4 hours. We went on rides, he got me dinner, and we got to watch some of the fireworks. I had my phone on silent but finally check in with my mom when i could. I told her i was down there with some friend(which was half-true, tons of people i knew were down there). I turned my phone off so that i could save the battery life and avoid them tracking me because my phone was low on battery and they literally tracked me down on my location. They started to demand my phone and i finally gave it to them where they proceeded to go through my messages and they didnt find anything obviously because I use snapchat to communicate with my boyfriend where he has an android and i have an apple phone. after she found nothing on my phone she gave it back and told me i was acting super weird. I was just trying to get away from them.

I finally turned my phone back on after 2 hours because the fireworks were starting and i was met with some text messages from my mom asking me to call her and I did. I was met with all kinds of screaming and when i got home they took my car,took my phone, called my grandmother, and now they are selling my car. They kept telling that if i want to be with trash(talking about my boyfriend) then I can not go to my school and continue to live as trash. I want to pay for my school now so that i dont have to abide by this stupid rule. I plan to focus on school regardless but now i might not even get to do that. They are convinced that I'm going to get pregnant and that my boyfriend is manipulative and purposly putting me in harms way because I want to see him even though my family doesn't agree. I dont have anywhere to stay but my dad wants me out of the house and I am about to happily go. I am also planning to go limited to no contact with atleast my parents during college so that i can focus on school.

TLDR; Parents are mad that i continue to see boyfriend after the demanded me not to
