In this friendship you'll both have the opportunity to do the hard work it's going to take to learn and grow as individuals. The problem between you will show up as a heavy energy, a certain level of control, possibly even guilt, that will bind you together and could drag you down. You'll secretly feel more vulnerable but will take the role of the more dominant friend in response.
Your friend may represent all the qualities that make you the most insecure -- personal strength, individuality, ambition, independence -- and you'll respond with coldness, or by exerting authority. This relationship could focus on responsibility and duty, rather than fun, lighthearted times together. Even though this sounds grim, you'll both have control over it. Gently but firmly resisting any attempts to control through fear or guilt will be important, as will facing down any insecurities that arise between you as friends.
