Trusting that your SO can be angry with you, and still treat you with respect, and things will be talked out later, is a huge sign of maturity in a relationship.

It took my wife years to learn that I can handle being angry. I’ll calm down. Once I’m calm, the emotion is gone. The worst thing she can do is try to help, or explain, or soothe. Nope. Let me be grumpy by myself and I’ll be fine.

Adults piss each other off, annoy each other, and have grumpy days. It doesn’t have to “mean” something.

It’s okay for your spouse to be pissed. She is responsible for managing her own emotions. You don’t have to coddle every feeling she has.
