Good advice already given here.
She is showing you that she is alpha mare, not you. Goal is to get her to respect you as alpha mare.
You need to push her away from you, like already suggested, with the end of your lead rope or a crop...whatever it takes. When you do it, you need to present the body language that you are in charge and mean it. You need to lean into her and move her. Don't step away from her, or you lost.
You are mimicking what horses do in the herd to gain hierarchy. Another horse would pin their ears, swish their tail and then bite or kick. Whichever horse moves away, loses.
However, also be firm, but fair. As soon as she moves away and does what she is supposed to do, no matter how small....at first....release the pressure. As she begins to understand, you can expect more and more.
