The angle between your signs — the square (90°)
The square is the aspect of tension: you want the same thing at the same time, just not the same way. This bond never falls asleep. It asks you to pick your battles, and makes you both stronger when it holds.
Your elements — Fire and Water
Fire acts, Water feels. One wants to move forward, the other wants to know what lies beneath. Steam, in every sense of the word.
Your rhythms — cardinal and cardinal
Two cardinal signs: you both start things. Plenty of initiative — and the question of who leads.
Your rulers
Aries is ruled by Mars, Cancer by the Moon. Drive and fight, facing emotion and shelter.
