In this situation it is best to go with the flow.If you are really close and true friends you will try an see it from your friends point of view.Who knows maybe someday you might have someone else as your best friend but if your friend stands with you through all the good and bad times and understands and trusts you then you really are true friends.If you really are good friends you will understand each other and after all fights are a part of friendship and we can only solve them by understanding each other.Fights like this will happen all the time.Sometimes we do not see it from our friends point of view.The two things that will not help is ignoring and crying it never helps.The best solution for both of you is that you should sit down and calmly without shouting or crying talk and understand each other and sort it out.
