My husband and I have been through many challenges in the past few years including living on opposite sides of the country due to jobs. So, communications is definitely important. However, we were starting to feel like ours was not to where we wanted it to be anymore. I came across a new book in the library...10 Lessons to Transform your Marriage by John and Julie Gottman (They also have another book something like And Baby Makes 3). This book is based upon scientific research that they have done on couples including video taping, heart rate monitoring etc. So, as they say in the book their advice is not based upon whims or their beliefs, but what they are finding works on many levels and can be scientifically verified.
ANYWAY, we started reading the first chapter and we both got into it. We ended up buying 2 copies of the book and sit down a couple of times a week when possible and read it together. There are also activities, etc. They have examples of communication that they critique, etc. that they record b/n couples. They provide feedback to the couples and have them try again.
The point of this was that we just finished the second chapter, which was all about conflict avoidance in relationships. It seems like it might be right up your alley.
We have found that we have only gone through 3 chapters so far and so much has already improved AND my husband actually likes the book as well and thinks it is really helpful. Turns out that we end up talking about the couple a lot and finding ways to relate to their situation and be able to talk about many of our own issues in a very neutral way when we are "working on the book". We say that we are going to work on it for 1-1.5hr and we often have many tangential conversations that take us well beyond that set aside time. The point is that our communication and desire to do so is improving. A lot of that is attributed to the examples that they provide, which helps us identify things we say in our own relationship. Further, there is the quality time we spend together "working on the book" and the increased communication in general.
Best wishes.
