Good stuff... Be careful about the books though...
What I mean is, it is great that you are reading and working on yourself. Just be careful not to intentionally leave books lying around for your W to see as a way of passively telling her that you're going to be a great H again because you're reading...
If she sees the books in your pile of books, then she does... Intentionally placing the books randomly around the house... not so much...
It will be your ACTIONS more than your words that will allow her to see you are making and effort and becoming a better man... one she can start to trust again... one that she might... eventually... forgive...
