Supernatural Story Finders

hii! so, i read a destiel-centric fic years ago (on either ff.net or ao3, i am not sure, its been so long.) and i honestly don't remember much, if i knew the title i probably wouldn't need to submit a request on here so yeah.... but i will try my best to make this search for you all as painless as possible and give as much detail of the fic that i remember so you can have better chances of finding it! This summary is super long, i am so sorry!
____________________ fic summary starts now:

It may or may not have had some Sabriel but i'm not positive on that. i just remember that Gabriel was there. i also remember it had a lot of chapters soooo yeah. this was not a short story, not by a long shot. and i don't know whether or not it is a completed work or not. though by now i am sure it is completed.

So what i remember it being an AU fic where Dean and Sam retire from hunting (possibly temporarily, i think Dean and Cas might have still been hunting together and the others were just doing research in the beginning?) and stay with Bobby and Kevin at the bunker (or maybe not?? i dunno, i just remember it being Bobby Kevin Sam Cas and Dean in some sort of homey place). Dean has started to come to terms with the fact that he has feelings for Cas. some things happened after that, but i dont remember what it was and then there angels appear. Fate specifically, and she comes to Dean and says that he is going to be the mother of a new race of humans, one that will be able to bear children despite their sex ////or something like that. Fate tells him that he'll be the one carry and birth the children, but he can't keep them all. Sam offers to take deans place because he feels that Dean has suffered enough in his life and deserves to be cared for but Fate says no because it has to be Dean who brings the new race of human into the world and fate personally thought that Sam wasn't strong enough for the burden/ or wasn't worthy. i think the latter, but i dunno.

Anyway, so the first few births at are quick and painless, but eventually progress and become painful and long. Dean gets to keep at least 3 or 4(?) of the children and has to go and give the others to childless people who really really want kids. he gets attached to one of the kids, because when Dean had given birth, it wasn't the right time for the couple that were destined to get the kid, so Dean had to keep it until fate said they were ready. he left a note when he eventually did drop off the baby at the couple's doorstep. at one point there is a particularly difficult birth that Dean goes through that requires the help of various angel because the angel of fertility/childbirth was unavailable or unwilling to help Dean and Gabriel was there to help as well. On one of the last kids Dean was having, he went alone off to do something or other and stumbled upon a mother with her young son who were being harassed by a mugger or someone with a gun/knife and came to their rescue, killing the guy hat tried to hurt the woman. i think he went with them to the hospital because he goes into labor due to the whole excitement of the situation. i don't remember what happens next but the woman and Dean become friends and they become a part of deans big family.

On the last pregnancy, Dean gives birth but instead of giving it to a stranger, Fate tells Dean to give the baby boy to Sam because he is stronger than she originally thought and throughout this whole journey Sam was envious and had internal turmoil because of the fact he couldn't have a kid or didn't have a kid.

Then i think a while or so later, one of the children Dean had been able to keep was supposed to become deaf at age five, and so he made a deal with Fate so that he'd take the kid's place and be deaf instead??? two years or so in, he has become completely miserable because of not being able to hear and being a part of everyone's life and at some point everyone doesn't even bother to sign for him when they are all talking fast and whatnot with him present. he gets severely depressed, i think maybe unintentionally isolates himself from everyone and eventually commits suicide. his eldest daughter finds him dead in his and Cas' room. they give him a hunter's funeral but a few years or months after he is resurrected and turned into an angel because of all the stuff he's done for heaven and didn't really complain much about his burdens, and that the angels were very grateful so he was granted a second chance at life but as an angel. (i think this paragraph may or may not be from another fic that has similar plot. there was another future!kid!fic where dean gets pregnant as well. but i dunno anymore. im prettyyyyy sure its part of this fic, so yeah..).
ANNND thats all i remember of that amazing fic.
I hope this helps in your search, thank you!
