Persephone and Hades are still married.

It is likely that Persephone dwelt with Demeter either upon Olympus or the earth.
Some myths say that for one third of the year Persephone stays with Hades, and for two thirds of it with her mother.
Persephone is Queen of the Underworld and the Isle of Blessed in the Underworld is her domain; she is also the Goddess of Spring, which is nice because plants live again.
Some myths say that for one third of the year Persephone stays with Hades, and for two thirds of it with her mother.
Every year, Persephone spends the autumn/winter (when plants die) with Hades, and returns with spring/summer.
Persephone once lived with her mother, Demeter. However, she was abducted by Hades. After an altercation between Demeter and Hades, it was decided that Persephone would resides with Hades for 3 months of the year. The other months of the year she lives with her mother.
Hades abducted Persephone, Demeter her mother went in search of her and her duties were neglected and humans started to starve, then Demeter learned where Persephone was and demanded her daughter back and Zeus agreed so long as Persephone had not eaten or drank anything while in the Underworld, but she had; so Persephone spends half the year above the earth with her mother and half below with Hades her husband.
Persephone stays in the Underworld for half of the year (six months) and is allowed to return to Olympus for the other half.
