Aries with Libra
Challenge, change, and passionate ideals keep both of you fascinated by each other. Aries' initiative and impulsiveness are nicely balanced by Libra's calm rationality and sensitivity to others' rights and needs.
Both of you are strong in your different ways, and have certain goals and ideals which you will not abandon - although Libra is more diplomatic about saying so. Both of you are restless spirits who need change and the sense that you are progressing with your lives. You are also both idealists and want to know that you are each doing your bit to help make the world better.
But your different approaches may sometimes strike sparks. Aries is fiery and "knows" intuitively when something is right, while Libra is airy and thinks things through in a logical way, taking others' opinions into account before reaching a decision.
This point of conflict is also a point of compatibility. Each of you needs the qualities the other provides. As long as you both have goals you can pursue individually as well as together, you can inspire each other to fulfil your individual potentials. Just try to avoid getting stuck in routines which bore you both.
