Anne's Responses to Henry's Letters

It's clear that Henry was very emotionally invested in this romance. But what about Anne? Without her replies to Henry's letters, what can we tell about how she felt about this all? Was she caught up by the romance and affection that the king showered her with? Or was she purely a canny political operator, playing the king to perfection? That's the million-dollar question, isn't it? There is so little of Anne in her own words, especially in regards to her love for Henry,. I would argue that Anne is actually in the driving seat here. She sadly don't have her replies to the letter, but we can infer what she is saying by his replies.
