specific dean/cas fic-au, no hunting, fbi partners, bobby as boss-FOUND!

[childlike-pearl.livejournal.com]

looking for a specific fic i was sure i had kept :( dont remember title or author or even the story but it was quite long and well written on ao3 with dean and cas as fbi partners and i think roommates as well, dean suffered from ptsd as iraq/afghanistan war vet, i think they may be get married in the fic? crowley is with internal affairs and has to vet the relationship, bobby as the section chief thinks they're messing around and dean quits for like a day and everyone in the fbi, ash, victor, gabriel etc support them. i think sam is married to ruby but she cheated, and is now having a baby and isnt sure who's it is.
i really hope my garbled mess makes sense to someone to recognise, would love to find this again!!!
thanks for any help
