Warren has never married, and does not think of herself as a person of commitment. In interviews, she has said that she believes that her lack of a romantic life makes her more peculiar as a songwriter. She was in a relationship with songwriter and record producer Guy Roche that ended in 1992 and claims she has not had another relationship since, commenting "I've never been in love like in my songs. I'm not like normal people. I'm no good at relationships. I draw drama to me — it's the Jew in me". Although she considers herself to be cynical regarding romance, Warren does not let this affect her songwriting and prefers to write alone, commenting "When I write with other people, the experience is different. You have to compromise, which I have problems with. I'd rather listen to my own mind".
