That James O’Brian interview linked earlier is very interesting.
He asks some good questions about her background but unfortunately doesn’t tie it together.
Jack reveals she’s only fallen out with her son’s dad once, after an article in the Sun where she said they printed loads of spurious accusations against him, supposedly from her. She claims that tabloids dumb her words down to appeal to readers, as an explanation for where the lies came from (she expands on this and seems to think she’s just too intellectual for tabloid readers). She claims she demanded the interview tapes (which conveniently, she didn’t get), and wrote a furious email which she then forwarded to SB’s dad as proof. She added “please tell your friends to stop slagging me off on Facebook!”.
So she’d obviously caused outrage with her lies amongst him and his friends. I imagine she’d lied impulsively, or used weasel wording or lying by omission, and is then frantically backtracking and blaming the newspaper.
Another interesting point was that she’d and her partner had a strict no googling clause with each other. This is very interesting and must be how Jack controls the narrative within relationships.
