Lord Voldemort never married and did not have a wife. He was obsessed with immortality and power, and relationships were not a part of his life. He believed that love was a weakness and that it would hinder his pursuit of power.
Voldemort's only known romantic interest was Bellatrix Lestrange, a member of his inner circle. However, their relationship was based on mutual respect and loyalty, not romantic love.
Voldemort's lack of a wife is a significant part of his character and contributes to his villainous nature. He prioritizes power and control over human connection, making him a formidable antagonist in the Harry Potter series.
