I found a tag for him on Ao3, dear! Here it is in case you want to follow it so you can find more if they are added. Right now, though, there’s only four that mention him! And your English is wonderful.

Who is Anthony Jay Crowley? by Gwindolyn

Anthony J. Crowley has amnesia but he's muddling through.

"They’d kept him over night at the hospital. He felt strongly that this was because he’d failed current history pop quiz they’d given him. He couldn’t remember the year for example. When he’d woken with a hellish headache he’d startled a laugh out of the no-nonse Nurse by proclaiming it to be the fourteenth century."

You’re Better Off Without Him by voidify

For some, it was Judgement Day (or, well, the day that should have been Judgement Day). But for Fred Sherwin, it was just another Saturday. The most memorable thing that personally happened to Fred that day was on his way to the Tube station that morning, when he gave a bit of advice to a white-haired gent who’d just been dumped by some wanker in a vintage car.

(The story of that moment, from Fred’s perspective— and the next two times Fred’s path crossed with that same man.)

One Foolish Heart by ZeroToWeirdo

"Aziraphale couldn’t help but think that while Armageddon had been stopped, the world had truly ended that day. At least, the world as he knew it."

With the world having not-ended, Aziraphale and Crowley suddenly find a whole future ahead of them. With that future came hope, as well as dreams that were under threat of coming true. If only they weren't both such dunderheaded fools about it, of course.

“...Therapy? You?” Aziraphale looked even more surprised, if that was truly possible. It was almost endearing to see him so baffled. “But… you’re you!”

“Really, angel?” Crowley took another muffin for the road. “After six thousand years in this body I hadn’t noticed. Consider it as an utterly selfish, very villainous take on self improvement.”

Crowley gets a therapist, Aziraphale's been in love for nearly eighty years, and there's some wing grooming. What more do you want?
