Is my mom right ?

My mom thinks I’m crazy and wrong for going to Texas with my guy friend. I’ve known him since my freshman yr of Highschool. He’s picking me up soon but am I crazy for going ? She literally says that if my stepdad finds out I might as well go live with him 🤦🏽‍♀️ . fiy me and him will be driving down there and then we’ll be buying a flight back for me .

I’m 20 & I won’t be using any of her money & she took away my car keys and house key and the money I kept safe for her. Car is mine so idk why she made a big deal of it.
