Any fic recommendations that start off with Spike already in another relationship but not with Dru or Harmony. The ones I can think of are...

Fall of the Night by Mabel Marsters
Lying Eyes by dreamsofspike (although a coerced situation rather than a proper relationship)
Changing History by Chosen
Moments in Time series by Laure Alexander

Thanks everyone
