Even when these two are apart physically, they are still together. Once they meet there will be this inseparable bond that is tied by their watery souls. It is kind of like if you had two glasses of water side by side, and then you dumped them in one glass, then tried to separate them again. Sure, you can pour half the water into the other glass again, but they will forever be blended. That’s what it is like when two water signs join, they never really every separate.
