Moving states at 18 with boyfriend?

So I’m 18, and have been with/known my boyfriend since I was 14. He might be getting an opportunity to move across the U.S. for an amazing job opportunity and wants me to move with him. I’m perfectly content with that decision and actually really excited. (I basically live with him now anyways) My job can transfer me to the same position where I’d be moving, we both would be making PLENTY of money to support our selves, and we both know we want this. His parents are fine with it, but mine are split. My mom refuses to even acknowledge this might be happening (even though this would happen next month), and my dad is perfectly okay with it. And if I do try to mention something about this to my mom she just put the idea down with all the bad things that could possibly happen. How do you guys think I should go about this? My boyfriend feels that if my mom refuses to support us on our decisions then I should just ignore her and leave her out of my life then. I think she’s like this because she still lives in her childhood home, has never moved, and yeah. My dad said she still wants control. I dont know
