Amy Winehouse‘s hubby admits he made her a junkie!

Now Blake Fielder-Civil plans to ditch the non-rehab-able Grammy winning diva in an effort to "save her life!"

"I introduced her to heroin, crack cocaine and self-harming. I feel more than guilty," Felder-Civil confessed to UK tab News of the World in a bombshell interview.  The former music assistant is in a London rehab facility after his release from jail November 5.

Winehouse nearly died last summer after suffering a seizure after a crack and heroin binge with Fielder-Cook that lasted more than 24 hours.

"It was heartbreaking, seeing someone you love more than yourself, someone you would die for, someone you would kill for on the floor shaking," he told the UK tab.

"I knew f—ing then that I had ruined something beautiful. It was all my fault."

When Fielder-Cook exits rehab at the end of the year, he knows there’s no going back even after she cheated on him with her manager’s assistant, Alex Haines.

"If Amy wants a divorce I’m not going to fight her for anything," he said. "I’m not taking a single penny off her."

That is if Wino survives the year – she’s had a series of near-death calamities stemming from drug misusage since bringing home 5 Grammys last Feb.
