Same sign
Partners of the same sign mirror each other: the same values, reactions and pace. That gives instant understanding, but also amplifies shared weaknesses - nobody balances out the extremes.
Elements
Two fire signs make a couple where things are always heated. You both love to act, get carried away and win, so the relationship moves fast and burns bright. The main risk is rivalry: when both want to lead, a fight over who is in charge can flare up over anything.
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.
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.
