Blake Fielder-Civil - who was sentenced to 27 months in jail last week for grievous bodily harm and perverting the course of justice - believes the only way he and the troubled singer can quit drugs for good is to move away from the temptations that currently surround them.
Amy's father Mitch told Britain's Sunday Times newspaper: "Blake totally gets it. He said to me, 'We can't carry on living in Camden. We need to move out to the country.' "
"If they do, they could have the most fantastic life together, with the full blessing of my family. Whatever happens, we won't be where we are now in two years."
Mitch, who has previously disapproved of Blake's influence on his daughter, says he doesn't blame him for his daughter's drug use.
He added: "He didn't coerce her to take drugs in any way."
"I wish he had. Because if he had she would most likely have said, 'I don't want to do it.' "
Mitch's comments come as Amy appeared to breakdown during a night out in London on Saturday.
She reportedly sat on the floor sobbing outside a bar before lashing out at a minder who tried to help her, screaming: "F**k off and just leave me alone - that's not the way I do things."
She eventually got up and headed for a nearby club but stayed just 30 minutes. A source said: "She was in a terrible state. She left by the back door and went home in tears."
"She had a black coat over her head and a swollen hand. She looked awful, like her world is falling apart."
