We get mad at dumb stuff because our “I don’t matter” belief gets triggered. Which, by the way, is probably what made your ex angry when you didn’t tell her what you wanted for dinner tomorrow. We all have some versions of “I don’t matter” beliefs that operate beneath our consciousness. Once they get pinged, we react in different ways, anger being one of them. What’s really fun is how people who become couples seem to be perfectly matched to activate each other’s “I don’t matter” beliefs. It’s uncanny. And, it can be a marvelous growth opportunity, if we can recognize it.
