From the comments section on Does a Pisces man ever end a relationship?
Do pisceans have a tendancy to want what they cant have? then not want it when they think they can have it?
Pisces is the dreamer, and for this sign, reality is always a letdown when compared to his fantasies. The sign of the Fishes is ruled by Neptune, planet of imagination, transcendance and delusion. Neptune is The Matrix, maya, the world of illusion. In the best sense, it is communion with God, where boundaries dissolve and one feels connected with everything in the universe. But most of the time, Pisces is the anti-Neo, swallowing the blue pill to remain in his delusion. He does not want to know stark reality.
The dirty secret about Pisces: He does not really want to be embodied. Pisces want to be Spirit, yet he’s stuck doing dishes and suffering through his day job. It is only when he plays his guitar or smokes a joint or falls for a pretty girl that he escapes from the Hell of the Mundane. The pretty girl is his Muse, inspiring him to write, paint, dance or daydream. Anything but to endure another hour of Here and Now. (Although the enlightened Pisces finds beauty in the present moment, for he recognizes the divine in as mundane an activity as sweeping dust from underneath the kitchen table.)
When the pretty girl is unattainable, then Pisces falls even deeper for her, for then his dreams cannot be ruptured by her humanity. Pretty girls bleed and poop and get needy and irritable. That’s no fantasy! Pisces is only called to create when his Muse is ethereal, when She summons him to reach to the heavens with his song.
So if the seemingly unattainable pretty girl starts giving off subtle clues that she’s into him, Pisces retreats. He knows that if he gets to know her, her human flaws will be revealed, and he will lose his inspiration. Once she becomes real, the bubble has burst, and he will have to look for another pretty girl to fuel his fantasies.
It is a cruel cycle that never ends until he comes to peace with being on Earth.
