She uses the lyrics of her unreleased songs to suggest the male (the 'you' in the lyrics) wanted out to avoid detrimental comment around his family name; that he has caused her pain; that he lied to her about his wife when he said he didn't care for sex with her and that the marriage was just a front, not real.
She ends by saying he asked to f*** her mind, but in fact he's just a f**ing liar, someone she used to know. Doesn't lead anyone to follow in her footsteps in such an encounter, or set of encounters!
