Final answer:
Ares, the god of war, did not have a wife but is famously known for his affair with Aphrodite, who was married to Hephaestus.
Step-by-step explanation:
The wife of the god Ares in Greek mythology is not explicitly stated as he is more famously known for his affair with Aphrodite, the goddess of love and beauty. While Aphrodite was married to Hephaestus, the deformed god of the forge, she had a well-known relationship with Ares, characterized by passion and turbulence. Despite this liaison, Aphrodite and Ares were not officially wed. In mythology, gods and goddesses often had many relationships and offspring with various partners, and the concept of marriage was not always as fixed as it is in human society.
