That old story about the tortoise and the hare was borne out in your pairing. You were the stolid tortoise, steadfastly working away on your ambitions, while your partner was the nervous hare, always hopping from one thing to another. Not only was that lack of focus annoying, it was distracting.
You were not able to get as much done with your mate around, and it bothered you that your sweetie seemed to hold you back from reaching your potential, rather than bringing out the best in you. It always seemed like you had to be the parent, the one to to take care of business while your partner flitted around socializing and having fun. You liked the control, but the responsibility was a drag. You kept doing it, however, because if you didn't, it didn't get done.You needed to let loose of the reins of responsibility. Your partner was never going to step up to the plate unless you had started backing off a little. You could have started with small things -- where were you going to go to dinner? What's the vacation spot for this year? Then moved up to more major decisions. It may have been a slow process, but instead it couldn't move forward at all because you two didn't start the ball rolling. Joint decision-making is a learned skill, and you're a good learner.
