I feel like I’m leaving in a story of Romeo and Juliet

I fell in love with a boy a year younger than me and I’ve never felt this way about anyone before and I’ve had a lot of relationship, anyway apparently I’m “too old for him” and his parents don’t want us together but I can’t just let go of him. His moms a teacher about school so it’s not like it’s easy to sneak around behind their back, I’ve talked to her before and she seems pretty set on him not dating for awhile. I don’t know what to do, should I move on or stay with him? What if he’s the one, it feels like he’s the one.
