Love Compatibility between Aquarius and Pisces

Aquarius and Pisces
- Love Compatibility Profile :

When Aquarius and Pisces join together in a love match, there is much compassion and creation. These partners are idealistic as individuals as well as they are together. Pisces flows with their dream-like surroundings, and Aquarius is constantly coming up with new inventions and ways of doing things. This relationship digs deep for the truth of the matter at hand, and both partners are always looking for solutions to problems. They both tend to be introspective. Aquarius can often be quick to judge those who don't share their vision, while Pisces is often too compassionate, even for those who don't necessarily deserve it.
Aquarius and Pisces make very good friends as well as excellent lovers. Problems are rare, but sometimes Aquarius can be too intellectual and aloof for Pisces, and Pisces may at times be too self-sacrificing and gullible for the Aquarian taste. Sometimes different reactions to a situation may cause a cavern between the two; Aquarius is quick to dismiss those who don't agree with their opinions, and Pisces takes on others' issues too quickly. On some occasion, the pair will have conflicts, but these partners can forgive and forget easily.
Aquarius is ruled by the Planets Uranus and Saturn, while Pisces is ruled by Jupiter and Neptune. Uranus focuses on iconoclastic ideas and innovative practices. Saturn gives this relationship the drive to act on these ideas and the ability to organize the details that will animate them. Jupiter is about philosophy, teaching, and understanding, and Neptune focuses on spirituality, so Pisces likes to truly understand new and exciting things, such as their partner. Whenever Aquarius comes up with a new idea -- as they so often do -- Pisces is eager to understand it on an intuitive level. This duo creates a complementary relationship deep in intellectual and emotional resources.
Aquarius is an Air Sign and Pisces is a Water Sign. This relationship is motivated by thought and feeling, respectively. There is always a lot going on, and this tends to be a very flexible and progressive union. When it's good it's very good, but when it's bad, communication is abysmal. Pisces likes to be where Aquarius's action and intellect stirs, and Aquarius can learn social tolerance and warmth from the demure Pisces. This team works well together. Although they may disagree, their differences of opinion don't last long. Conflicts may arise because of Pisces's need for emotional support and tenderness, and Aquarius's preference for ideas rather than romance. Aquarius is a Fixed Sign and Pisces is a Mutable Sign. Aquarius initiates new ideas and changes, and Pisces will accept these as long as they have an assigned role in bettering the relationship. When these partners get together, they won't argue over who gets to take the credit for their achievements. Both Signs are better at starting things than ending them; if Aquarius gets bored with the relationship, Pisces will soon follow the example and want to move on.
What's the best aspect of an Aquarius-Pisces relationship? It's their mutual interest in cultivating knowledge and accepting modern and cosmopolitan ideas. They are well matched in their enthusiasm, energy, and desire for a sincere, open and honest relationship. Their common interests and reciprocal personalities make theirs a compatible relationship.
