By the middle of the 1970s, Tina Turner's personal life and marriage began to further deteriorate. Ike's alleged drug use led to increasingly abusive behavior toward Tina. The abuse increased because their act was losing popularity, record sales were down and Ike was placing the blame on Tina. She abruptly decided to leave him (after an unsuccessful suicide attempt) while in the middle of a tour in 1976, with nothing more than thirty-six cents and a gas station credit card. She spent the next few months hiding from Ike by staying with various friends and relied on food stamps to exist.
Tina credits her newfound Buddhist faith with giving her the courage to eventually strike out on her own. Around this time, she appeared solo in a memorable cameo as the "Acid Queen" in the film of The Who's Tommy rock opera. Tina finalized her divorce in 1978 after 18 years of marriage, accusing Ike of years of severe spousal abuse and rampant drug addiction in her autobiography I, Tina, which was later made into the film What's Love Got to Do with It?. To put the marriage (and Ike) behind her, Tina left the marriage with no money or property, asking for and retaining only the use of the stage name Ike had given her.

If you get a chance, her bio is worth reading - she put up with way too much shit from goofy Ike.
