If you don't mind self-recs, I wrote a story that goes AU half-way through 513, where they do get married - Flames (http://arlad.livejournal.com/46998.html)

It's a one-shot, but I absolutely love this one; "Wedding Night" by Phobosgirl: http://qafvault.com/weddingnight.htm It's Justin and Brian's wedding night.

Wow, I can't believe no one's mentioned this one yet: Choices by [livejournal.com profile] england13

technically, it's a wip, but so far all indications are a go for the wedding!

also, [livejournal.com profile] freakykat has a series tagged the Gus Universe where Brian and Justin get around to getting married 10 years and two kids (counting Gus) later.

I'm tediously tagging entries and recalled a couple more: Announcements (http://www.livejournal.com/tools/memories.bml?user=chering&keyword=Announcements+1-26&filter=all) by [livejournal.com profile] chering and [livejournal.com profile] fansee (chapter 1 is the very last entry, btw), and Unbroken Circle (http://msjudi.livejournal.com/84241.html) by [livejournal.com profile] msjudi (phobosgirl on bjfic.net).
