Looking for an old fic...

[samara-007.livejournal.com]

I am looking for a fic that is at least  six or seven years old and possibly older.  It was one of the first fics I ever read, and I'm curious if it ever got finished.  What I remember is that Spike and Buffy had a one night stand kinda thing and Buffy was pregnant.  There was a demon that kept showing up to help them out, although later in the fic we find out that it had been not so nice to Angel & company in LA.  I remember a specific scene with Xander and Anya getting married and everyone dancing at the wedding.  There was a big vampire attack when Buffy was about to give birth, and somehow the Buffy and Spike from that dimension got removed to another, safer one where the baby was born and of course, later discovered to have magical powers.  But in the original dimension, Buffy died and in his grief, Spike went evil again.  At what I remember as the end of the fic, the inhabitants of the second dimension where Buffy now lives kept seeing flashes from the other dimension.  Sorry this is so jumbled; I wish I remembered the turn of events better!  I think the author's name might have been something like grey or greyer, but I could be completely wrong on that!
