She is angry right now, cause she was called on her behaviour. I bet deep down inside, she knows she is in the wrong.... most people do...... but she is embarrassed and too prideful to accept your apology (and you had no need to apologize!). But you were being the bigger, better person. She sounds messed up. Some people have few or no role models of good behaviour......, you were likely hers. Hence, their bad behaviour in many situations. some people never learn how to apologize..... they have never been taught that "I'm sorry" is an important part of the vocabulary. It's really unfortunate. YOU have done nothing wrong, so just go about your business with your head held high and continue to be the kind person you are.
