If you choose to stay in the relationship and make it work, it is important to forgive, but not forget. Another water sign, Scorpio, never forgets — and will probably bring up past indiscretions twenty years later. But a Pisces … a Pisces can empathize with her partner’s difficulty abiding by the reality principle (meaning that Saturn may be a pain in the ass, but at least he governs commitment and discretion), and conveniently “forget” she’s been hurt, only to let herself be walked on again.
Sun-Neptune or Pisces people can be prone to self-sacrifice, taking care of a homeless musician-addict, giving him a place to sleep, money for beer, sharing a bed even though she has no idea where he spends his other nights. She’s “saving” him. “What will happen to him if I don’t provide for him? He’s so talented … if only he got his act together, he could make something of himself.”
Her idealism is notable, but as the aphorism goes, “There’s a Pisces born every minute.” Being suckered into giving cheaters a free pass … that’s not her highest calling.
So, how does Pisces draw the line between compassion and being a doormat? If it’s in your nature to make sacrifices, to give of yourself because if anyone is hungry, you too suffer, then channel this yearning into works in the public sphere, not into your intimate relationships. Is this easy? No. Obviously, if you’ve got Neptune or Pisces planets in your seventh house, sacrifices in one-on-one relationships are par for the course. But I firmly believe we have a choice in how we express our archetypal dynamics. You can’t change your Piscean nature, but with a combination of consciousness and will, you can steer your ship on the right course.
