WAIT!!!!! question!!!! what exactly did she do wrong? i understand that you are furious, and honestly i cant blame you. i mean you did have a valid reason for everything! if you are saying that she was the one that said no forget hanging out cause you needed to change, then you shoulda changed and called her and asked if she was ready to go! i doubt she really ment it, and even if she did you coulda gone over in what you were in unless the were covered in deer blood!

everyone knows girls can get that way just to get you worked up or because its that time![&:]
put yourself in her shoes though. you argue friday, then YOU called it off on saturday. then if you didnt call her saturday night after you were at the party or at all sunday, then wouldnt you probably figure that you were still upset about friday? she just tried to guess and she guessed wrong! (nothing new)

honestly man, talk to her, explain what happened. you have the visual markings from being jumped, and you have a very valid reason for not calling sunday! (stay calm)
why did you get jumped?
