A story similar to 'Master'?

Looking for a fan fiction similar to 'Master'?

It is season 2, Dru is still with Spike but they have problems, he takes Buffy prisoner and the Scooby gang looks for her and she is still in a relationship with Angel i think, and Spike cannot make himself kill her and then he realizes slowly why and Buffy baits him into fighting/killing her because she cannot take it just not doing anything.
