Need some advice😬

Okay so there's this guy that I love..not like, but love. I'm 15 and he's 17. He's very different from your average 17 year old, meaning he's not a sex addict, he doesn't party nor drink, and he's a virgin. We love each other so much but my parents won't let us date because he's two years older than me. And I don't know what to do because I've never felt this way about someone and I never want to loose him. Please let me know what I should do
