Hi, Me again , right this one, Buffy doesn't know Spikes alive, now I can't remember, if its just willow/Kennedy or the rest of the scoobies who try to hide it from her, even though Buffy is heart broke missing him. I've read so many stories over time, then stopped for a while, then had to get a new laptop, so everything I knew is gone, bookmarks and such, so there's several I am trying to remember shame details are so vague x

That's uh... really vague, heh.

Would it happen to be With All My Heart by spikeslovebite?

Summary: Post Chosen. Fed up with their lies and deceitful ways, Buffy has broken off from both her friends and the Council, but she doesn't know that they are still meddling in her life. She doesn't know they set up a slayer to pose as "Buffy" in Rome, nor does she know that Spike is back. She's living a quiet life mourning her lost Champion when the Powers-that-be decide her that her duty is not done.

In it, the Scoobies (minus Dawn) keep the fact that Spike is alive a secret from her. She lives at beach house, having nothing to do with the Scoobies or slaying, and is heart broken and still missing Spike.
