This could be a case of Hard Love, but at the end of the day it’s all about miscommunication. The “problem” is the blend of Mercury/Neptune energies. That will never bring your thoughts straight from your brain. They have a long way to travel through all your instincts and gut feelings.
Eros is not so emotional but very perceptual, and he likes to brighten love. Saturn (because he is in Pisces) recognizes that, but can’t produce the right reaction and guide it into a flow. It takes time to understand the brightness of love.
I’m sure you cherish the moments if instantaneous happiness when this aspect is in effect. You may notice them at first.
