Direct Answer
Your fighting issues with your spouse stem from the involvement of retrograde planets and their placements in your chart, particularly Jupiter retrograde in the 6th house and Mars retrograde in the 4th house. Venus, the key planet for marriage, is placed in the 11th house but in Sagittarius and is closely linked with Saturn and Mercury, adding challenges. The retrograde Jupiter indicates past-life karmic issues impacting trust and judgment related to family and spouse, while the retrograde Mars in the 4th house creates ego conflicts and emotional unrest in home life. These planetary influences cause misunderstandings, ego clashes, and difficulties in maintaining harmony with spouse.
