You've gripped too hard in your past relationships, and it's caused tension between you and your lovers. They felt stifled, ready to escape ASAP. You felt jittery and panicky, as if letting go even a little bit would cause everything to fall apart.
Ironically, however, it's exactly this possessiveness that has triggered most of your problems. Yet how could you make peace with your difficult lovers? You chose partners who were passionate, intense, powerful, yet a bit unpredictable. You couldn't always count on them to be where you liked, or to be as loving as you'd prefer. Sometimes it seemed that they were even getting off on the power a bit, as if you were playing a part in their ego trip.Now it's time to get a hold on yourself, and stop displaying all those unflattering emotions. Learn to play it a little bit cool. Exhibit your self-confidence instead. Pay attention to your goals. Your ideal mate admires someone self-sufficient, someone who achieves. This is you to a T when you don't distract yourself by dwelling on your insecurities. Don't mess the next one up by demanding promises. Instead, hold on loosely and focus your attentions on yourself. Your lover will be devoted once the pressure's off a bit.
