Your Uranus opposes his impulsive, sexy Aries Moon, and trines his Jupiter and freedom-seeking Aquarian North Node. You make him feel youthful and rejuvenated. As a Gemini, he is at heart playful and childlike. You each owe each other something, most likely having played these roles before in an unrequited, romantic situation. You both have the free will to write your scripts now.
Extramarital affairs create painful betrayal and extremely bad karma.
Think carefully about the repercussions. As a proud and proper Capricorn Sun and Venus, you certainly are ambitious and go after what you want, but you also need the stature of living by a strong moral code of ethics. Living a lie and loving by deceit will eventually take its toll on you, physically and emotionally. His marital problems are his alone and he owes his wife the loyalty and respect to resolve them with her before moving on with you or anyone else. Your sensitive, psychic Pisces North Node shows your karmic path in this lifetime is learning to be compassionate, understanding, and empathetic to others.
