I'm 16, he's 19, no one "approves"

Sami
My SO and I met last year at school, he was a senior and I was a freshman, there was nothing wrong with the relationship until he turned 18. Both of our parents don't like the idea of just being friends, and our friends don't like the relationship in general. Once I turn 17, next year, we'll be able to legally date, but I have no one to talk to about the relationship problems/concerns and we have to sneak around to just meet up or even text. 
If any of you have any advice, please do comment. We're extremely happy together and have been together for 14 months today. This is just a little vent, and opinions are welcomed.
