An Aquarius Sun often spends years being asked why they can’t just be normal. Another Aquarius isn’t going to ask. They’ll want to hear more about your idea for the shed, the cause you’ve taken up, or your theory about time. Neither one will take it badly if you need a week alone or if you have a friend who’s an ex. They can design a relationship from first principles, and sometimes it’s a very good one, with fair chores, odd vacations and a wide circle of people who feel at home around them.
Two people, both at one remove
The trouble is that an Aquarius, when hurt, tends to step back and observe. If you both do this, you might end up with two very calm people discussing a problem from a great height, while what’s actually going on stays down on the ground. Love between them may be real, and go unsaid for months. Each might also be quietly sure that needing reassurance would be disappointing to the other.
And since it’s a fixed sign, disagreements can get oddly permanent. Two people defending their principles can stay stuck for a long time, and they may also confuse being stuck with having integrity.
An experiment worth running
You like experiments, so try this one: for a month, once a day, tell each other one feeling with no theory attached. Sad counts. Glad counts. No explaining allowed. Touch counts too, and regular physical affection can do a lot for two people who live mostly in their heads. Agree when a rule has stopped being useful, and change it. You invented it, after all.
Same Sun doesn’t tell you much about warmth. Compare your Moons, and if one of you has a Moon in Cancer or Taurus, they might be asking for something the rest of you hasn’t noticed.
