Learn to love your anger and what it is teaching you about yourself, your past, and how you want to move forward in the future.
When anger is quick and easily resolved the issues don't stick around much. Try and process the little anger while it is happening. Try and take the BIG ANGER offline, out of the relationship for a moment, and come back with some ideas of how to do things differently.
We all learn about anger at a very young age. Before we can understand the language we are being given verbal and physical clues about what is a right thing to do and what is a wrong thing to do. For most of us lucky ones, this guidance is done without the injection of anger or physical abuse.
