How can i argue with a girl but not get blamed for it(10 points)?

I think best way to do this is to stay calm, i know it's very difficult to stay calm when your pissed, but if you really want to win and get your point across then first let her do all she wants, let her get it all out, and when she's worn out and tired from it all approach her nicely and calmly state out the facts to her of what is bothering you (ways you could do this is maybe holding her hand or sitting with her, hugging her). But make sure to do it absolutely calmly, yu don't want to add fuel to a diminishing fire and make it blast! Then when you're done try and make her realize that all her screaming and shouting, or whatever way it was that she chose to respond in the first place, was wrong. And then eventually she would apologize, because she would compare how tender you was, and how rude she was and feel guilty for being so irrational.
