In terms of building trust, my 5yr old son broke trust the other day. The following day, he was put in the exact same predicament. And I did not trust him. He assured me that he was trustworthy. I would not believe him. After a while i resigned myself to the fact that I had to trust him, hoping that he had learnt his lesson from the night before. So what i'm saying is that you're only as good as your last innings. Staying trustworthy is all that you can do. Your morals and values are what make you a man or woman. If you can trust yourself, then others will. And you don't need a book for that.
As for pulling away or towards your wife, well, your natural inclination is going to be towards familiarity. And thats ok, but this appears an opportunity (note that i stated opportunity) to get out of your comfort zone. Most people will disagree with me here, but do something that you've always wanted to do, but always put off. The one thing that brings out the inner child in you. This is the real you. Hopefully you can share it with her and she can see you for who you truly are. Be you.
Just cos things are going right, doesn't mean that they were always wrong.
