long distance relationships

hey all, my boyfriend and i have been together for six months and i met him at my holiday house, because that's the town he lives in so obviously we don't get to see each other much, considering he's 300km away. what makes it harder is we're 15 and 16 and don't have the freedom to just drive to see each other every weekend. however we're both really set on being together for a long time and we've already talked about him moving to my city to go to uni after we finish high school. do any of you have stories of you and your s/o like this? especially if you're now married or living together!!
