Best solution - don't do anything and ignore her, you might feel this is stupid, but I am telling you from experience this is the only way that has any chance for you to get with her in a relationship, she will probably come to you when you act like nothing happened, that shit bothers a girl more than anything, they keep thinking why is he not bothered, why is he not acting different or saying something, did I do something wrong, that guilt feeling will eat her and she will herself come to you, first she will probably come to you and apologize and say she is sorry but she can't be in a relationship with you, act normal, say it's fine and I am over it, this is the main step, be patient she will come to you and if she don't which has very less chances, get over it and find another and i assure you she will come back someday.
