What did Ariadne do for Theseus?

Ariadne gave THeseus a harpin that turned into a sword named Anuklusmos, or Riptide in English,to defeat Ladon, the dragon, that gaurds the tree of golden apples of immortality.In return,Theseus promised Ariadne to marry her.When they sailed off together for home they stopped to rest on Calypso's island.Here THeseus sailed off the island without Ariadne while she was sleeping.For those of you who don't read Percy Jackson, Ariadne provided Theseus with a ball of twine (given to her by Daedalus), with which he could navigate the Labyrinth.Ariadne was the daughter of King Minos of Crete. When Theseus was brought to Crete as one of the sacrifices for the Minotaur, Ariadne gave him a spool of string so that once he killed the Minotaur he could find his way out of the Labyrinth. In return for her aid, Theseus took Ariadne with him when he left Crete; however, he later abandoned her on a deserted island.
