12. “You should have known better”

This phrase can be especially damaging when it’s said in the heat of the moment. It suggests that your partner should have been able to read your mind or understand something without being told. Even if your partner made a mistake, this statement can make them feel like they’re being unfairly blamed or criticized for not meeting an expectation they didn’t even know existed. Instead of being constructive, it creates a sense of guilt and failure. In a calm, rational conversation, it’s better to explain what you needed or expected. This approach fosters understanding, while phrases like “you should have known better” only build resentment. Communicate your needs clearly and give your partner a chance to understand before placing blame.
