“Rielle – probably naively – now realizes she had held onto a false promise that if she continued to take part in the cover-up John had engineered, they’d be together in the future,” a close source told The ENQUIRER.

“She was willing to protect John for the sake of the child. She agreed to allow a crony of his to claim he was the baby’s father, and she even kept the name of the father blank on the birth certificate.

“But now she can see there’s never going to be a future with John – and she feels he’s lied about his promise to keep Elizabeth from trashing her in the book,” the insider divulged.
