Buffy is cruel to Spike and he leaves her

Hi everybody, I'm looking for a fic where Buffy goes too far and Spike leaves her. I think it's during season 6, during their affair : she goes to his crypt and leads him on, being tender with him and telling him how great it would be if she loved him... then tells him coldly it will never happen. Spike is furious and orders her to leave. But in the end they get back together, because Spuffy always wins ! I think it's a few chapters fic, but I'm not sure. Does anyone have an idea ?

I think that might be What Big Teeth You Have by Slaymesoftly: http://spikeluver.com/SpuffyRealm/viewstory.php?sid=37204&warning=AO-AdultsOnly

Yes, that's the one ! Thank you so much !
