Post BtVS Buffy and Spike go down a tunnel/dark hole where she plans to convince him to be with her.

Hi, 
I am looking for this older post-BtVS fic where Buffy and Spike aren't together (though Buffy wishes they were) and the two of them get stuck in a deep, dark tunnel/hole (Buffy's intent) and they hash things out. I remember that Buffy thought that Spike had his eyes on some other chick when, in reality, he didn't. I can't seem to find this anywhere, my thanks to anyone who knows what I'm talking about with this fic. 

we own the night by okdeanna it on her website

I just checked OKDeanna's site and it said that it was "under maintenance".

Hi, thanks so much for the fic find. It's officially been found. Her website is under maintenance and her lj is f-locked but it is on a few(?) lj communities. Thank you so so much for coming up with the name.
