It's important to note that Ariana was not his wife in the traditional sense. She was his younger sister, and their relationship was deeply tragic.
Here's a breakdown of the story:
* Ariana's tragic life: Ariana was a powerful witch but suffered a traumatic event as a child, leaving her mentally and emotionally scarred.
* Secret love: Dumbledore was in love with a woman named Gellert Grindelwald, who shared his desire for a world ruled by wizards.
* A tragic fight: Ariana was accidentally caught in a fight between Dumbledore and Grindelwald, leaving her deeply traumatized and unable to control her magic.
* Dumbledore's remorse: This incident led to a bitter falling out between Dumbledore and Grindelwald, and Dumbledore dedicated his life to protecting the wizarding world from Grindelwald's ambitions.
* Ariana's death: Ariana eventually lost control of her magic and died, leaving a deep wound in Dumbledore's heart.
So, while Ariana was never his wife, she played a pivotal role in shaping Dumbledore's life and choices.
