If you don't know what the boundaries are in your relationship, establish them before you end up in an uncomfortable situation. Remember that after high school, life changes dramatically.
Once you know your boundaries, demand that they be respected. Sometimes the strongest boundaries are mental, or emotional. That's not to say that you can't form a lasting relationship at a young age, it just means that you need to be ready for long distance and a whole new set of problems as an adult.

Try not to make a relationship your whole world because it will limit your experience in other areas of life.
