Blake Fielder, the former husband of Amy Winehouse, has denied that he "ruined" the tragic pop star.
The Rehab singer and Mr Fielder wed in 2007 and had an on-off relationship even after their marriage ended two years later.
Mr Fielder was widely criticised after Winehouse was found dead of alcohol poisoning in 2011 for having introduced her to hard drugs.
Speaking ahead of a new documentary about the singer's life which will be released next month, the 33-year-old told The Times Magazine that he feels guilt over what happened.
But he added: "I feel like my own legacy as far as Amy goes is that I ruined this amazing person.
"If I genuinely believed I (ruined her) I probably would really struggle getting through day to day.
"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.
"She wasn't a happy, well-adjusted young woman, you know, and I find it disrespectful to imply I was some Machiavellian puppet master."
Mr Fielder also said he would like to speak with Winehouse's father Mitch, who once described Mr Fielder as "the biggest low-life scumbag that God ever put breath into".
He said; "I'd like to speak to Mitch and genuinely, genuinely plea for his forgiveness (for any) parts I've played in what has occurred, but I won't take responsibility for Amy passing away because it's not fair."
