If you really love her that much, then you should respect the decision that her parents have made, because if you plan on having any future with her, then you are going to have to be on her parents' good side. I have had this whole "16 problem" as well, before I was 16, and dating (er...trying) without letting my parents know was a nightmare. Just give it time, and if you can't wait, then she's not your "true love".
