The loveliest thing about Crowley and Aziraphale’s relationship is how they fell in love with each other over 6000 years. Since they are demon and angel, respectively, they’re not limited to the human concept of love. It’s not about physical attraction. Their very first moment of affection happened when Azi protected Crowley from the rain with his wing. From that moment on, it was clear he cared about Crowley’s welfare intensely.
It was just the beginning of an endless development of how actions spoke louder than words to their hearts. Every time they performed miracles for each other, every time they saved each other, every time they did little actions immersed in ineffable affection, all of this is what made their hearts skip a beat, which we can totally observe through the heart eyes, heavy sighs, long stares and pet names. The more they live and do things for each other, the more they are in love and can’t live separately.
This is precisely why Aziraphale says Crowley goes too fast. He likes how Crowley saves him, performs miracles for him, shows how much he cares about him. This is how love works for Azi. He doesn’t need anything else because he has everything he needs in this dynamic. This is what makes his heart go faster, this is what “attractive” means to him.
Meanwhile, Crowley dies every time he sees Azi’s puppy eyes. He wishes he could be evil as a demon is supposed to be. But he can’t. The moment he sees Azi’s purity, he’s compelled to be a better demon, something he hates and loves at the same time. To Crowley, the process of falling in love is based on Azi’s reactions. The more Azi sighs and smiles at him, the more Crowley is in love and determined to keep trying to make Azi happy. It’s his main designation.
So, this dynamic works because it’s precisely endless and grows stronger and stronger as the time goes by. They need each other’s respective proofs of affection to keep on feeding up their relationship, which means the concept of love for them is entirely platonic. Nay, let me rephrase that. They took the concept of platonic romantic relationship to the ultimate level.
I believe this is why Neil Gaiman keeps saying they were not portrayed as a couple according to our standards of a romantic relationship, yet they’re very in love with each other. It’s precisely because they’re so deeply in love in such a beautiful, unusual, ultimate way that mere human beings are not able to even begin to conceive the beauty and the depth of this love.
Lastly, am I saying they’re totally romantic aces that took the concept of love to the nirvana level? Am I saying aces are like demons and angels? Am saying we should adopt the ineffable husbands as ace icons?
Yes Maybe. Very well, I rest my case.
