I just wanted to mention a book I've been reading that I've found really helpful. I've been working through the DBT Skills Workbook (green book) and that has been helping a lot. 

But I came across a book a few weeks ago that has been really helpful about taking my dbt skills and helping me apply them to my relationships in my life. It's called the "The High Conflict Couple: A Dialectical Behavior Therapy Guide to Finding Peace, Intimacy, and Validation." I feel it's a good tool to build upon any DBT work you may be doing. It is a bit dense in my opinion. I've been trying to read a chapter every few days and sometimes I go back and reread things but I honestly feel it's been one of the most helpful tools I have ever discovered. 

It is geared towards romantic relationships but I feel it can be applied to all relationships.
