Affair fic

Hi all! I'm looking for a fic I vaguely remember reading before and would like to find again in the fic they are all human Spike is married to Drusilla I know in some scenes its kind of like a flash back to where he and Buffy met before she found out he was married. The first chapter of the story I think is Buffy being stood by Spike I think she ahs this inner monologue where she compares herself to a whore because she's living in a house he bought her and what not. Later on in the fic she calls it off and starts teaching at a preschool/kindergarten I think I'm not quite sure. If any of y'all could help that would be wonderful!!

The only fic I could think of I've only skim read and I don't think it totally fits (but he does stand her up in an early chapter, and she was/is a school teacher). So it might be worth checking -
Desire and Deception by Ashlee.

Sounds like "Dirty Little Secret" by Noelle here at TSR.
