According to her tweet that started all this. He sent her text messages.
He flat out denied it under the polygraph test.
That's actually the one thing that has the potential to be any kind of evidence to backup one side of the story.
And he completely denied it. That would seem to me to be a pretty stupid denial, if he knows he really sent those text messages to her. She could easily refute it with proof.
I feel she should now release the text messages if she's telling the truth.
