Why did wife kill herself?

It appears as though you are referencing the popular song "The Perfect Drug" by nine inch nails. The lyrics of the song feature a man expressing his love for a woman, but the relationship is toxic and brings out his worst tendencies. The chorus features the refrain, "You're my perfect drug, a lethal dose." This symbolism is frequently used to refer to toxic relationships that end in tragedy, such as the woman killing herself.
