Since he first laid eyes on her, Spike has been in love with Rarity. We all know it, hay, most Equestria knows it by now. The unicorn in question has been acting as though she felt the same way, saying sweet things and acting so lovely to the baby dragon. But as years have passed, Spike's seen the big picture and doesn't want to have his emotions toyed with.
Though maybe he doesn't know the half of it.
(Sequel- "All Things Come To Be Loved And Lost")
Inspired by the song "Don't Love Me That Way" By the long gone, but not forgotten Prozzak
