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 cardinal - initiators used to starting things and leading. Together you launch shared projects easily, but you need to divide roles, or each of you will pull in a different direction.
Aries in love
In love, Aries is the pursuer. It enjoys the chase, shows feelings openly and wants an equally honest response. Boredom and coldness put out its fire faster than arguments do. Aries needs a partner who is not afraid of its energy and leaves room for excitement.
Cancer in love
In love, Cancer needs to feel safe. It opens up gradually and looks after its partner like family. Cancer hopes for the same tenderness, attention to small things and certainty that it will not be abandoned. Harshness and indifference hurt it more than it shows.
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.
