The source continues that LeAnn is "losing it" over the book and her fears that they might split. "LeAnn desperately wants to believe him. If they don’t last, she looks like the biggest loser in the world.”
And while LeAnn refers to Brandi as "toxic," it still bothers her that Eddie had such a hard time ending things with Brandi.
“LeAnn has always worried about Eddie being attracted to Brandi,” reveals the source. “It was devastating for her to learn that Eddie didn’t leave Brandi, that he wanted both of them.”
