Square
Signs in a square share a modality but belong to different elements. There is a lot of energy and attraction between you, and friction too: you solve the same problems in different ways. These couples grow through conflict, as long as they learn to talk it through.
Elements
Fire and water make steam and passion. The fire partner acts on impulse and speaks bluntly, the water partner feels deeply and remembers hurt. The attraction can be very strong, and so can the clashes: one feels smothered, the other feels wounded. This couple has to learn to handle each other gently.
Pace and temperament
Both signs are mutable - flexible and quick to adapt. There are few hard conflicts in this couple, but also little certainty: one of you will need to make decisions and see things through.
Sagittarius in love
In love, Sagittarius wants a partner and a fellow adventurer. It falls for people it can grow with, laugh with and explore the world with. Jealousy and control make it pull away. When Sagittarius feels free, it stays by choice.
Pisces in love
Pisces loves romantically and selflessly. It needs emotional depth, tenderness and the feeling of being understood without words. Pisces easily idealises its partner, so disappointment hurts it especially. It needs someone who treats its feelings with care.
Why one sign isn't enough
Sign compatibility compares only the position of the Sun. Even two couples with the same signs have their Moon, Venus and Mars in different places - which is why it comes easily to some and takes work for others. Exact compatibility is calculated from both partners' birth charts.
