“Blake was furious with what she wrote about him,” confided the spy. “Every word Blake read enraged him because he’s pretty thin-skinned.”

The ENQUIRER obtained a copy of some of Gwen’s diary writings and the informant warned, “When you read it, it’s a cry for help.”

Among the buzzwords in her scribblings were: “Misery,” “Make Me Like U,” “Asking 4 It,” “Used to Love You,” “Red Flag” and “Me Without You.”

“I was fine before I met you … I was broken but fine,” Gwen penned.

“It seems that she fears that she’s going to end up alone. She thinks that she won’t have someone to love her, which is odd because she’s just begun a new relationship,” said nationally recognized handwriting expert David Liebman.

Gwen, 46, and Blake, 39, began their whirlwind romance last November following the breakdown of their marriages but The ENQUIRER revealed photos of them looking miserable after a Feb. 3 fight.
