The couple said that they left the centre to only 'get a guitar' from London.
Defending himself for the first time, the video assistant insisted that he loved his wife so much that he can never be the cause of her woes.
He added that Winehouse's problems have been exaggerated to a large extent.
"Everyone thinks that everything that's happened to Amy is my fault and I'm portrayed as the bad guy. But I love her so, so much. She's so precious to me, she's my wife and I want to take care of her, that's why I'm taking her back to rehab," the Daily Mail quoted Fielder-Civil as saying.
"We only came back to London to get a guitar and then we're going straight back.
"It's not because we were too weak to stay. If we were going to send a message to Amy's fans we would say don't worry, she's being looked after. The reports about Amy and drugs aren't true to that magnitude," he said.
