A very shadowy thought of yours eventually pulls you to the dark side. It comes with so much pent up anger, resentment, or pain. This is the place of final destruction. A destruction in a relationship or a situation. You could self-sabotage, but compassion and love will help you leave this unhealthy situation without hurting yourself or the other people involved.
Sun in Gemini: Spirit is overwhelmed by possibilities.
SIMPLY PUT: Burning the bridge, is just a understatement.
