'I didn't ruin Amy': Drug addict former husband of tragic singer Amy Winehouse claims he wasn't responsible for her early death

The singer's intense marriage with Blake Fielder-Civil was known to be the inspiration for Back To Black but he is also blamed by many for leading her to an early grave in 2011.
He admits introducing her to drugs but claims she had her own problems with alcohol and bulimia before they met. But he fears he will never escape the stigma of being seen as a corrupting influence on a singer treasured by fans worldwide, which has already torn his family apart.
