Despite all differences the common trait in Aquarius man and Pisces woman is that both show extreme behavior but in completely different ways. While Aquarius man thinks too much the Pisces woman will feel too much and initially both would be impressed by each other though long term relationship will be a completely different proposition altogether.
However, the inability of Aquarius man to get deeply involved in anything can easily leave the Pisces-born woman high and dry since she is too clingy and dependent on him. At the same time such dependent nature of the woman will not be liked by the man. Fact remains that he can never offer the cozy nest that is the dream of Pisces woman.
Aquarius-born man is jolly and all the times preoccupied but is also a great thinker. Once he chooses the lover, he is loyal and faithful to her and becomes a great protector of his lady love. Pisces woman on the other hand lacks self confidence but has a delicate, sensitive, and emotional nature. Once she finds her true lover she will completely put her trust on him.
Initially the sexual life will be matched by great excitements and soft touches making the relationship comfortable but latter when the initial fire extinguish, the relationship may get a little boring and unworthy of continuance.
