Here are books I may recommend to people who want to change their relationship with anxiety.
Hold Me Tight - Dr. Sue Johnson
This may be my favorite book to recommend to couples. The underlying framework gets right to the heart of what a secure connection between two people looks like.
The Seven Principles for Making a Marriage Work
This book has some very concrete and practical things a couple can do to avoid disconnection and to find a more fulfilling way to interact with one another.
