Use 'I feel..."' statements. Basically start every sentence with 'I feel', for example: 'I feel disrespected when you yell at me.' The goal of this is that you cannot argue with how someone feels. If she still argues and tells you that you're wrong for feeling that way, then I'm afraid nothing will help you.
