Her parents won't let us date

I am a freshman in college and I really like this girl who is a junior in highschool. I met her in the summer and we hung out all summer long. When i let for school, which wasnt far we wanted to date, but her parents wouldnt let us. I am now transferring to a school that is much closer to home and we still want to date. Her parents still wont let us. We still talk even though her parents dot want us to, bt now they dont even want us to hang out. I tried everything. I even emailed her mom to talk to her about it, she was very nice about it but still said no. we even were thinking about sneaking behind her parents back, but we dont want to ruin her relationship with her parents. I dont Know what else to try. I really like this girl and have never felt this way for a girl before. She means a lot to me and really care about her. Does anyone have any ideas on how i could get her parents permission?

To be honest there is no way to get permission sometimes it's like a Romeo and Juliet type relationship. I was once in the same position I was 19 and she was 17. Her mother had no problem with it, it was her father who wouldn't allow it. No matter how I proved myself to be a good gentleman he never approved of it. In the end we just kept it a secret and waited til she graduated then got together. If you really love her then she is more than worth the wait. You'll just have to settle for seeing her around the clock and in secret until she graduates and she can choose to date you as she wishes.
