What you're describing wouldn't be so good for early gaming, you want her feelings and emotions towards you to be positive if you want to get anywhere with her. In a relationship having a willingness to walk away is always a good thing though.
Like you said if you have an argument or whatever with your girl just walk out the house or wherever it is you are and drive/walk away. If she lets you get that far
Another thing, never enter into a shouting match or raise your voice. You can argue calmly, regardless of how she's acting.
