"I Don't Think About You" is written by Sean & Andre Davidson of the production duo The Monarch, singer Jessica Ashley (professionally known as Harlœ), and Vanderbilt pianist Michael Pollack.

Harlœ, who travelled to Nashville, Tennessee in 2016 to collaborate with Clarkson, told her that the song was inspired by a situation in her life where she was old enough to finally realize and conclude that the relationship 'didn't work out, and you're kind of a douche, but thank you for making me a stronger human.
