I do think people are forgetting, sometimes willingly, that Aziraphale is JUST as heartbroken over the rejection as Crowley
They did not walk out of there with Crowley destroyed and Aziraphale bummed but getting over it once he was in the elevator. Aziraphale went to Crowley all giddy and excited because he really thought this was finally it, this was finally their chance to be happy, and he sees it as Crowley taking that chance and stomping on it. H wasn’t lying when he said he needed Crowley, he DOES, and now he thinks Crowley chose his hate for heaven over his love for him just as Crowley thinks Aziraphale chose his devotion to god over his devotion to him
It wasn’t as simple as “Aziraphale rejected Crowley” they both think the other rejected them it was essentially the messiest mutual break up you’ve ever seen
They’re both completely heartbroken and do not see the part they played in their own heartbreak. Both thinking THE OTHER caused it. It’s such a mess. It’s SUCH a mess I cannot STAND these two
