Dionysus.
He married Ariadne.
Athena or perhaps Dionysus. It isn't clear.
Some myths say that he "forgot" her, others that Dionysus ordered him to do it. Some say that he wanted to marry her sister Phaedra more than her. Whatever the case, he abandoned her and married Phaedra, and Dionysus married Ariadne. He dreamt that she would marry a god.
She never really 'dated' anyone since she decided to never marry. Some people thinks that she liked Dionysus.
Dionysus means "God of Nysa", Nysa was the birthplace of Dionysus.
Dionysus did not die.
