My dad is my worst nightmare

Listen i am 19 years old. I have been dating my boyfriend for almost 6 years and all of a suddenly my dad want to continue controlling my life and making it even more extreme and saying i can’t go to his house cause i need to respect my self? My dad not even religious nor goes to church but he believes in god i do too. I know my relationship is not about sex and stuff like that. Even if i do have sex im on BIRTH CONTROL! today i got caught going to his house because i go to his house instead of going to college because i take online classes for the summer. He want to show up cry and say im changing. I get it he loves me and explained he doesn’t want me pregnant or losing track of my study but god damn he think my life revolves around my boyfriend. I am smart i know my boyfriend is different. We both tell each other everything and are bestfriend. It always my dad trying to control where i go this and that. I cant even sleepover with my friend because he think ima sneak out for god sakes im 19. He mexican and all he says is he doesn’t want me turning like the American people. What does that even mean brooo
