Hello all, does this ring any bells? Buffy lives with and is engaged to a mortal. He has no idea she's a slayer. The story starts out with a seemingly harmless slim young dark man, using mind control to overcome slayer abilities and strength to torture and kill them. Buffy comes up against him and to her horror, finds herself struggling to defeat him. Spike comes to her rescue. She's stunned to see him. He comes to her home and Buffy's boyfriend can't stand him. I think Buffy also has a cat named Spike, that forms an instant attraction to the vampire Spike. Demons begin coming from all over to do in Buffy, it's around Christmas in the story timeline and in a battle, Buffy's tree gets shoved through her ceiling. Spike remains near so as to guard Buffy, and drives a wedge between Buffy and her new man. The story is ultimately Spuffy of course, and I think that Spike has lost his soul.

In No One Other Than You by Tibialisant a lot of those elements exist. Her cat's name is William, though. Buffy is a martial arts instructor and living with a programmer named Tom. It's no longer available on the web, unfortunately. The big bad is not the man though. It's another vamp made by Dru. She just sent the man after baby slayers.
