I wouldn't have given her the books, Tank. I keep mine hidden. The danger, of course, is that she may think you are following a script to "get her back." She may interpret your changes as temporary and nothing more than needy pursuit. I hope I'm wrong for your sake.
If you can interact with your wife, without coming across as desperate and needy. By all means, do it. Giving her a taste of what she can't have creates powerful attraction. As long as you can exercise detachment during your meetings, her attraction to you will grow. I'm not there yet myself.
The key is to give her a little taste, then take it away. Keep her hungry for more. If she thinks that she can gorge herself on you, any time she wants, she will lose interest.
It's easy to give advice; it's much harder to follow it.
