The singer, who has had Blake's 'girlfriend' Sophie Schandorff to blame for making her think twice about her marriage, is yet to see her beau since he entered rehab, according to sources.
The 'Back To Black' hit maker, whose husband was released early from jail on a condition that he'd mend his ways at the 'Life Works' centre, had declined to pay Blake's 30,000-pound rehab bill, according to a pal.
"When Amy found out Blake had been in contact with Sophie it was the final straw," the Sun quoted a pal as saying.
"He expected her to fund his rehab while he was contacting his other woman. Amy hasn't visited him in rehab and is refusing to take his calls. It looks like it's over but we've been here before. He's talked her round plenty of times before," the pal added.
However, Blake, who was sentenced to 27 months for thrashing a pub landlord and attempting to cover up his act, said: "She hasn't dumped me. We both love each other and will be together forever. We have spoken on the phone and I'm expecting a visit from her any time now."
