She is testing you, not uncommon. It NEEDS to be addressed. Take a crop with you next time but use it more as your "arm" if you will. If she does not respect it still, use it on her, not whipping but usually a swift slap will get their attention. A crop longer than a riding crop would be in your favor, you will have more space in between you and the horse but use what you can. Horses have a place in their "herd." She is trying to establish her dominance over you as she would in a herd. Don't think human, think horse. An older horse would kick her butt!
