The three things driving this pairing
Element — fire and air
Fire and air feed each other. The Aries moon processes feeling as impulse and heat; the Libra moon processes feeling by putting language around it. Different, but not at odds — each gives the other something it does not generate on its own.
Modality — both cardinal
Two cardinal moons both want to be the one who decides how the feeling gets handled. Nobody is refusing to engage; you are both engaging, at the same moment, in different directions.
Aspect — opposition, 180°
Opposites are not strangers. You are working the same theme from opposite ends, which is why the attraction is immediate and the argument is always fundamentally the same argument.
The heart of it
Opposite moons are working the same question from opposite ends, and here the question is: how much of me survives contact with you? Aries answers by staying entirely itself and saying the thing immediately. Libra answers by reading the room first and finding the version of the thing that keeps the peace. Each of you is genuinely better at what the other avoids.
The recognisable failure is quiet. Aries says the sharp thing, feels finished, and moves on. Libra absorbs it, smooths it over, says it is fine, and files it. Aries then believes the relationship has no conflict in it, right up until Libra produces a fully itemised account of eleven months of small things Aries has no memory of.
What works, and what breaks
What works
Aries teaches Libra that a direct statement does not end a relationship. Libra teaches Aries that timing is not the same thing as dishonesty. Both lessons stick.
What breaks
Aries reads Libra's diplomacy as evasion. Libra reads Aries's directness as aggression. Neither reading is generous and both feel obvious from the inside.

Are Aries moon and Libra moon compatible?
The attraction is strong and the friction is structural. As opposite signs they share an axis, which makes each recognisable to the other, and they meet it with opposite instincts — Aries confronts, Libra harmonises.
Why do opposite moon signs attract?
An opposition is the same theme approached from two ends. Each sign carries the capacity the other left undeveloped, which registers as magnetism before it registers as difficulty.
What is the main conflict between Aries moon and Libra moon?
Directness against diplomacy. Aries expresses immediately and considers it resolved; Libra defers to keep the peace and accumulates what was deferred.
How can Aries moon and Libra moon get along better?
Libra saying the small objection at the time, and Aries treating a pause as consideration rather than as evasion.
