Limits for dating in college? PLEASE HELP?

So. ive been dating this girl for about 4 months now. Next year, i will be a junior in highschool, and she will be a freshman in college. We have decided to continue dating, and try for next year. We will see each other every other weekend normally, seeing as she is only about 2 hours away. we can hangout for the weekend. I am just wondering what our limits should be. I know we will both miss out on some of highschool and college because of the relationship. For someone who maybe has experience in the topic, what type of stuff are we both going to be missing out on, and what are the things that we will not be able to do that we would normally if we were single. We are both just scared because we have no idea what to expect. Thanks for the help:/
