It's not TammyAsh666 story. This one had chapters. I remember that story too! It was sadly on Vampire Kisses site which no longer exists.

Buffy is jealous except if I remember correctly: Dru and Spike went out then broke up then Buffy and Spike were together, something happens he is back with Dru...and then I forget, but I know Spuffy were back together in the end. A twist!!! I think Angel was Buffy's brother maybe? I could be thinking of two fics there.
