I wasn't responsible for Amy Winehouse's death: Ex-husband

London: Singer Amy Winehose's former husband Blake Fielder-Civil has rejected suggestions he was responsible for her descent into addiction and eventual death at the age of 27.

Fielder-Civil, who has a history of dependence on heroin and crack, has often been accused of introducing Winehouse to hard drugs and being partly to blame for her early death from alcohol poisoning in 2011, reported The Guardian.

"I don't think I ruined her, no. I think we found each other and certain people need to realise that she did have other addictions before she met me," he said in an interview ahead of the release of Winehouse's documentary "Amy".

"She wasn't a happy, well-adjusted young woman... And I find it disrespectful to imply I was some machiavellian puppet master," Fielder-Civil said.

Winehouse and Fielder-Civil were married in 2007 and continued an on-and-off relationship after their marriage broke down two years later.

They were both lost and damaged people, Fielder-Civil said. The 33-year-old also claimed he was still in love with Winehouse, four years after her death.

"I'm in love with someone, who is not here. I think about her every day. I'm a bit stuck now, thinking, 'How do I move on?'"

The long-awaited documentary, made by Senna director Asif Kapadia, will be released on July 3.

The film charts Winehouse's life from her childhood in Southgate, north London, to her death in 2011, plagued by addictions, depression and bulimia.
