Even though you're 'just friends,' you'll feel incredibly attracted to each other, as if when you meet, you're irrevocably caught in each other's orbits, for better or for worse. Your friend will feel fascinated by you, as if they can't get enough of you. There will be an addictive quality to the time you spend together, and there could easily be a sexual element to your relationship, whether or not it is overt.
In this friendship you'll learn a lot about each other and yourselves, that's for sure. For your part, you'll learn about your own tendencies toward possessiveness and control. You are learning to be more self-aware and thoughtful about your actions. This aspect between friends can indicate a strong creative bond; one where you each explore the limits of your inner artistic selves.
