Posted to her MySpace in April 2009, it was intended to be part of The Family Jewels, however, it didn't make the cut. It was then meant to be included on die Life, and it was again intended for Electra Heart after her second album concept was changed. However, it again didn't make the cut.
Diamandis performed the song live 59 times between 2010 and 2011, and 3 days in a row in February 2012 before Electra Heart was released and not on the Lonely Hearts Club Tour.
Jealousy, was supposed to be on The Family Jewels and then, performing it live on tour last year you talked about it being on the new album -
Yeah, and then I just scrapped it. Poor old Jealousy! [laughs]. I hope another artist picks it up. I would like that. It’s a really good song.
Various stems snippets leaked in April, 15 2019.
The theme of leaving first: "I never say a word, leave you before you leave me" links the song to:
Radioactive: "But baby, I'm the one who left you, you're not the one who left me."
