Amy Winehouse’s husband says he’s ending the couple’s 18-month marriage because divorce is the only way to stop the talented songstress from killing herself.

Blake Fielder-Civil, who is currently in a rehab clinic as part of his early release from prison, says he feels responsible for Amy’s well-documented drug addiction and will not reconcile with the troubled singer when he leaves the Life Works Center later this month.

“I dragged Amy into it and without me there is no doubt that she would never have gone down that road. I ruined something beautiful,” Blake, 26, said in an interview with News of the World over the weekend.

“Now I have to let her go to save her life. I am not abandoning her. I am doing this out of love.”

He adds, “When I see pictures of Amy and the state she’s in it tears my heart out. It scares me to death that I can’t fix Amy. But for her recovery I have to leave her alone. I will do anything for her and that includes walking away.”

“There are still reasons that Amy and I don’t like to be sober and if I go back to her I am basically saying, ‘It’s all right to kill yourself Amy.’”
