Why is Oberon mad at Titania in "A Midsummer Night's Dream"?

In "A Midsummer Night's Dream," Oberon is mad at Titania primarily because of a dispute over a changeling boy. Here are the key points:

The Changeling Boy

Oberon and Titania are arguing over a young boy, a changeling, whom Titania has taken under her care. Oberon wants the boy to be his knight and to accompany him in the forest, but Titania refuses to give him up. She is deeply attached to the boy because his mother was a devotee of her order, and she had promised to care for him after his mother's death125.

Accusations of Infidelity

In addition to the dispute over the changeling, Oberon and Titania also accuse each other of infidelity. Titania accuses Oberon of being infatuated with Hippolyta, the queen of the Amazons, while Oberon accuses Titania of loving Theseus, the duke of Athens12.

Emotional Motivations

Oberon's desire for the changeling is driven by jealousy and a desire for Titania's undivided attention. He feels threatened by the strong bond Titania has with the boy and the boy's mother, which he perceives as a rival to his own relationship with Titania2.

Consequences of the Dispute

The quarrel between Oberon and Titania causes chaos in the forest, affecting the natural order and the lives of other characters, including the Athenian lovers who enter the forest134.
