Marriage

Hey so I’m 17 (about to turn 18 in two weeks) and my fiancée is 19. We’re getting married right after my birthday and moving in together however my parents don’t know yet. They met him in December and told my family that we’re not dating and he won’t be a part of this family. So we continued to date afterward... has anyone else went behind their parents back and got married or married someone their parents didn’t like? How has it turned out? Anyone just cut their parents off mostly or completely???
