Like others I followed her because she can be plain speaking about women's issues, but she sets alarm bells ringing I honestly think the stuff she says about BPD not being real is pure projection.
I have a few friends with borderline personality disorder (which I've no doubt is caused by trauma, is a stigmatising label and is misdiagnosed in women a lot) and Jess so reminds me of them. Very good at presenting the veneer of empathy and beibv quite charming when it suits her, quite sensitive to criticism, very scattergun in their manner of communication and lots of dramatic stories of trauma and abuse that are either talked about with inconsistencies or mentioned once then never again. Bad decisions or decisions they regret always dressed up as someone else's fault, an abuse or trauma dynamic, publicly very intense relationships and very all or nothing/black and white thinking.
I had no idea she had been married to a man. I did know her wife is younger than her - I remember seeing them celebrate her 23rd birthday I think, and thought it odd then even if the age gap isn't that big. Even smaller age gaps are creepy when one of the couple is very young.
I also don't think she ever says anything particularly insightful. It's very much a constant steam of polarising Internet soundbites. That said, I bought her most recent book out of curiosity so if i ever get round to reading we'll see.
