George Michael reportedly tried to end his relationship many times with his lover Fadi Fawaz before his death.
New reports have also emerged that suggest that the couple were estranged for over 18 months before the superstars death.
A source said, "On more than one occasion George told Fadi he no longer wanted to see him, but each time they would find themselves back in touch."

The source continued to tell The Sun, "George was so kind and generous, but he said to me many times that his biggest weakness was he could never say no to anything - sex, drugs - he had that sort of personality.
"In many ways he was quite a vulnerable person, because he always said yes. He never stood his ground."
Fadi, who found George dead on Christmas Day at his home, has previously admitted that their relationship was "very complicated".
