Which Buffy villain are you? I’m Anyanka (Anya), which I think fits pretty well.

Your job was purely to grant revenge on men by their angry female lovers. Unfortunately you’re mortal now, and also in love. You’re getting the hang of being human, but you’ve still got some rather strange habits that give away your old, evil nature.

Translation: You were an angry, bitter, man-hatin’ girl before, but now you’ve got a schmoopy and you’re happier than ever and you try not to mess it up. (Link courtesy of anon.)
