You did fine. It sounds like you were strong. Now give her time and space to fully process that you are going and moving on. No reason to quibble about possessions. You have no kids and you said yourself you had few things to disagree about. It doesn't necessarily have to be over forever, but for now it is...so proceed accordingly. I hope the move works out for you.
You cannot be lonely if you like the person you're alone with. Dr. Wayne Dyer
