The unnamed ambassador’s wife in You Exist Too Much (the debut novel of the Palestinian-American writer Zaina Arafat) is, like the unnamed narrator of the novel, both bi and Palestinian-American.
She has a husband, who is an ambassador, and a son.
The ambassador’s wife and the narrator meet through her mother, who is friends with the ambassador’s wife. The narrator drives the ambassador’s wife (who normally has her own driver) home one night. The ambassador’s wife invites the narrator into her home, and they kiss and have sex, starting an affair whilst the ambassador’s wife is on her own, since her “husband was overseas for most of the summer”.
The narrator notes that she “only saw the ambassador’s wife at her house, usually in her bedroom”; despite their affair, the ambassador’s wife admits to “still” being “very much […] in love with her husband”.
When the narrator tells the ambassador’s wife that she loves her, the ambassador’s wife stops taking her calls; they then argue at a party, and the narrator says: “Why are you acting like you don’t even know me?”. Then, she yells at the ambassador’s wife: “You bitch!” and apparently never sees her again.
