DR is the upgraded version of DB. If you are interested, you might like Keeping Love Alive tapes. It comes with a workbook and helps to keep you solution oriented. You might wait until you are finished with coaching.
Follow your DB coach's advice. Just listen. It is so hard to just do, but it is a great skill to master. You might find some of your viewpoints changing and your understanding of your wife erally increase.
One thing you MIGHT like to do, is find a place to journal what you learn about your wife as soon as you can after the conversation. It's something that you could do here.
