Astrology can offer guidance in love and marriage by examining the compatibility between two people's birth charts. Key factors include the positions of Venus (love), Mars (desire), and the Moon (emotional needs), which reveal how each person expresses love, handles conflicts, and seeks connection. The 7th house in your chart also shows your approach to committed relationships. By analyzing synastry (how the charts interact) and composite charts (the relationship's energy), astrology can highlight strengths and challenges in a partnership, helping you understand compatibility and improve the relationship dynamics.
