My theory is 2 options
Option A, this is all a ploy to break his mind to the level that he tries to kill her or hurt her and then gets locked away, and then no one would hear his side like what happened to her so he suffers like she did.
Option B, she figured out that he infact didn't write the article and it was sensationalised, he may have been kind to her or she read his writing in prison and saw that there was a big difference between his normal articles and hers. So while she now understands that, she still believes he needs to take responsibility and suffer for not standing up for her. Now she wants to morph him into someone devoted and obsessed with her, someone who will spend the rest of his life doing what she wants for forgiveness. Whether or not she wants him for utilitarian, sexual or romantic reasons she just wants to dominate him and make him her property.
That's what I'm guessing at least rn.
