As a recurrent card, the 5 of Swords signifies an imbalance within the relationship. In contrast to the imbalance represented by the 6 of Swords, this may point to a personality imbalance. One person is taking a more prominent role, leaving the other in the shadows or making them feel relegated to the background. The person in the forefront becomes the "STAR," while others in the background take on supporting roles, reflecting a dynamic within the relationship.
Considering your mention of a long-distance relationship, the 5 of Swords could suggest a potential drift apart. This could be attributed to one person shining or standing out, while the other feels unable to keep up or overshadowed. βοΈπ
