my couples rarely (if ever) end up together.
let's seeeee
in one of my books, the guy is with the girl at the end--but he was with her at the beginning, too.
in another one, the couple never gets together, and the possibility of them ever getting together is pretty squashed. there are a few kisses, though.
in another one, the guy has two love interests throughout the thing and at the end is alone.
in another one, they end up together at the end
in another...most definitely NOT together.
the one I'm writing now barely even has a love interest.
but with the exception of the one where they do end up happily ever after (and the one where all hope is squashed, to an extent) none of mine are about those relationships.
