Aquarius has an uncanny way of disassociating the self from emotions. One might think they're stuck up, but that couldn't be further from the truth.
They live in their heads, and that's where all their moods are, too - right where they can think about them! That detachment isn't an act, but it is deceptive.
Is your Aquarius pal still here? Then the Water Bearer is probably hooked! Given the number of friends they have to choose from, they don't lack for other places to go!
If you find you have endless things to talk about, and Aquarius reveals a bit of that soft, vulnerable underbelly, you may have found your soul mate!
