For a conclusion, it's open-ended, but pleasurably so.

The story reminds me of a Florence and the Machine song which features two lovers whose passion is so strong, they continue to love each other as ghosts. I can't remember the name of the song now.

It also reminds me of the ghosts in Thornton Wilder's play "Our Town," who live on in graveyards, but in a distanced ethereal way, such that the real world seems a dream to them.

Either way, very nice. You know it's a good story if you don't want it to end. :)
