My best guess is that you 2 miscommunicated about something. well here's the number 1 rule to relationships and friendships... communication!!! If you don't communicate with her, then you'll never figure out what she's feeling, and you'll probably never resolve the problem.
Note- there is a difference between talking to someone and communicating with someone. You can talk to a wall.. but the wall won't understand what you're saying to it. If you communicate with your friend.. she will understand you, and you'll learn to understand her. The 2nd most important thing about relationships and friendships is compromising. Out of all of the miscommunications that happened, you can fix most of them by compromising so both of you will be satisfied.
