seeking_spike | Looking for a fic...

So I've been up and down the entire list of stories on fanfiction.net and can't seem to find this one story I know was there.
I cannot recall the name of the story or the author, but I remember that it begins in the cave where Spike got his soul. The basic premise of it is that the PtB are playing matchmakers with Buffy and Spike. They tell him he will die (or maybe it was fade away? - I can't remember) unless he can find someone who can love him. I remember that every time Buffy sees him he vanishes like a ghost.

I first found it on fanfiction.net, but it's no longer there (unless I'm missing it, somehow). If there's anyone who can help me by finding it elsewhere, I'll appreciate it.
