Looking for any fics where Buffy is a normal human girl and Spike is either still a vamp or a slayer and of course they get together.

Gardens of Oblivion by Addie Logan
Summary: After discovering her husband has been cheating on her, Buffy Summers decides to get a little revenge before she tells him good-bye. However, her plan takes an unexpected turn when the man she meets is more than he seems... (AU, not all human)

On Sinister Attraction

Vampiric Love by Vampirische Liebe

Summary: AU fic. Spike is Buffy's Vampire Boss. He notices her but she's not interested. Sparks fly when she discovers the truth about him and tries to stake him. NC-17. (This is supposed to be a bit tongue-in-cheek, so I hope that comes across okay)

There's Goldenusagi's Sideways, right here at the Realm, wich starts with human Buffy, although very soon she becomes the Slayer; and there's At Your Service, by Dampersndspoons, at the Bloodshedverse.

Blood and Fire by Addie Logan.

There's Real Me by CG Again here on TSR as well as Marching Us All to Our Graves by Arina Summer, on this site too.

Meet the Pratts, Finding William Pratt and Being William Pratt all three by Verity Watson on the Bloodshed Verse --- incredible story!
