It was released on February 17, 2016, as the first single from Gnash's third extended play, "Us" (2017). The song peaked at number ten on the "Billboard" Hot 100. Outside the United States, the song topped the charts in Australia, a first for both Gnash and O'Brien, and peaked within the top ten of the charts in Austria, Belgium, Finland, Norway and the United Kingdom.

Gnash enlisted San Francisco singer-songwriter Olivia O'Brien with the help of JB, who originally wrote the song, to provide the vocals for the track. O'Brien had already worked with Gnash, having covered his song "Disposable". Gnash originally released the song on July 26, 2015, on his SoundCloud page. It was released commercially on iTunes on February 17, 2016, becoming the lead single of Gnash's extended play, "Us" (2016). This song express the pain and sorrow that love can bring. While the male lyrics from Gnash express deep feelings that still remained for a girl who had broken up with him, the female lyrics by O'Brien portrayed another girl with a combined feeling of unrequited love and jealousy toward the aforementioned boy whom was hung up on his ex. The music video for "I Hate U, I Love U" premiered on March 7, 2016. "Time" was negative towards "I Hate U, I Love U" labeling it as one of the worst songs of 2016 and writing, "Forget The Chainsmokers and Halsey's chart-conquering smash 'Closer'—the most depressingly zeitgeist-defining song of 2016 is gnash's piano ballad 'i hate u, i love u,' with singer-songwriter Olivia O'Brien, which inexplicably rose to the Top 10 of the Hot 100 this year. The singsongy melody is obnoxious as an ice cream truck jingle, while the lifeless production drains it of any energy." In 2017, the song was nominated for a Radio Disney Music Award for Best Breakup Song.
