It was released as the album's second internationally released single in 2004 (see 2004 in music) and became Lavigne's third most successful single . It peaked higher than "Don't Tell Me", the album's first single. In the United Kingdom, it reached the top five, in the United States, it peaked at number nine, doing better in Mexico where it peaked at number 1. The RIAA certified "My Happy Ending" platinum in January 2005, making it Lavigne's second platinum single after "Complicated" (2002). The song contains the word ****, which generated a small amount of controversy. This song was once very popular on Radio Disney, and because Disney is targeted toward children, the word **** was replaced by stuff in the radio edit of the song. "My Happy Ending" is also considered one of the most popular breakup songs among teenagers today. Structurally, the song is written in 4/4 style and has a repeated hook in both the chorus and in the intro and outro. The song's bridge is hailed as the strongest bridge in Lavigne's songs both vocally and lyrically.
