Do not wait for a lightning bolt. If you want this, you build it.
The two of you
Pisces. You feel real when you do not have to harden yet. People see the softness, and someone who understands before the explanation.
Aquarius. You feel real when you are allowed to be slightly apart. People see the difference, and the idea that arrived before the room was ready.
What wears it out
A demand to be definite before you are ready drains you. So does a hard room with nowhere to retreat.
A room that wants you normal drains you. So does closeness that asks you to merge.
Pisces feels it first and explains later and adapts quickly, and may not finish. Aquarius needs to talk before it feels real and does not like to be moved once settled.
The signs sit next to each other. The feeling is friendly more than fated. That can still be a good love. It just will not carry you. Together, it shows up as what they do not say. The other way around, it shows up as money and what they keep.
This is the answer people want before anyone knows a birth time. Two real people have more than a sun sign. If it matters, cast both charts.
