Moon opp Mercury, very tight too. Conflict between head and heart. You have a beautiful relationship and you feel it in the heart. This negativity comes from you focusing, mentally, on past hurt. Change your mind, do something that keeps it busy and draws energy away from the past hurt. Maybe focus on a puzzle?
You might feel this to a lesser extent with a wide orb, but, be careful not to put your foot in your mouth, be more tactful. This makes you take things too personally. Are you a witty person?
