Was there something in your past that you were still holding on to -- guilt? An obligation gone wrong? A psychic bruise from a bad situation?
Whatever it was, the baggage weighed down your life, and your relationship. You couldn't see your lover's motivations and emotions clearly, and thus you couldn't relax. They were suspicious and hard to please; certainly not a lot of fun to be around. There may have been a pattern you were continuing, and you felt a lot of guilt, or there could have been something in your partnership that you kept secret. The words connected to your relationship were grim: wariness, deceit, fearfulness.You needed to look clearly at the connections between your past and this situation. What led you to chose the lover you went after? Who in your past brought out similar emotions in you, or treated you in a similar fashion? By enacting your old patterns, you were trying to fix something that was unfixable. What's past is past. You could have moved on, if only you could have let go of the negative emotions and embraced the progress that was being offered you. It's never too late to center yourself in the present; from this location you'll make more current choices.
