As a pisces, I always emotionally "swim away" before any sign physical break. Once I'm gone it doesn't long before my "single actions" force them to break up with me. I would much rather have it that way anyhow. Why would I, as a sweet, innocent pisces, wanna break up with someone?? :p
As for Scorpio's.. for me they are everything I want to be, secretive, detectives, suspicious. I can't keep secrets to save my life, and suspicious? I would kill for that quality, might make me less of an "astrological doormat" as I've heard pisces be deemed. And there's no question when a scorpio wants you. They wear lust in their eyes, like a pisces wears sadness.
