Adonis

Some beautiful dude that Persephone and Aphrodite fight for on live TV, Jerry Springer to be exact.  Anyway, you can find all that information through  Lulu Publishing.  

But, the ruling/the judgment turns out that Adonis spends one-third of his time with the one, one-third of his time with the other, and gets to spend one-third of his time by himself so he doesn't go crazy.  Justice, alas! There's a similar story with Persephrone. Except apparently in this version, she has to spend half of her time with one of her kids and half of her time with the other.

This story is sometimes about the Spirit of Adonis.
