Some future possibilities?

I've been with my boyfriend for about a year. We're only in high school, but don't judge us on that. We're both really mature for our age. Before we started dating, we were best friends. Now that we've given the whole dating thing a shot, not only are we STILL the best of friends, but we're also pathetically in love with each other. Here's the issue, though. We're both Juniors now, and will be expected to start looking into colleges. We want to pursue our relationship after high school, attending the same college, but we want to do completley different things. Any advice?
