I [m19] am having issues with distance with gf [17]. Any advice could help.

So I am in college and she is in high school and as if that's not bad enough I only see her 2-3 times a week. This is mostly because her parents aren't very fond of me because I am older. Needless to say we've hit a sort of rough patch in this 8 month relationship. She's already broken up with me once because of the distance and hates not being able to see her, but I convinced her to take me back but now im scared she is having second thoughts. I don't want this relationship to be burden on her but I really don't want to let her go. I'm hoping within the next year her parents will come around, and then this relationship will make her happier. I need advice. I have no trouble waiting because I am thoroughly convinced that she is perfect for me and I have all the time in the world. I would really like advice to help keep this distanced relationship rolling. Anything would help right now

My questions are: do you think she will end it again? If she will how do I prepare myself If not how do I keep this relationship going? Anyway to get her parents to like me more?

tl;dr: distanced relationship taking its toll or her and by extension me. How do I keep this relationship going?

Also throwaway account since she reddits
