Do you have access to a large round pen? If you do, free lunge her. There is no "abusing" in this method. If they think this is abuse, they need to do more research on horses lol.
Use a lead rope, and get her to run around the pen. Always make sure you stay out of kicking distance, becuase a lot of times, when you get the horse to turn inside to you, then send them away, they protest. You never have to even touch her with anything.
Once she is listening to you well, her inside ear will tune in on you. You control which way she turns, and how she turns (inside or outside). Eventually, she will start to be submissive to you. Some horses lick their lips, it can be very subtle in some horses. When you feel she has been listening to you and responding to your actions, turn sideways from her, as this no longer confrontational and you are now letting her come back into your 'herd'.
She will either walk right up to you, or stop. If she walks up to you, she won't run you over. She now views you as the lead mare and she won't come into your space. You should be able to walk around the pen and she will follow you, without a halter and lead, and she won't be pushy doing it.
Lettin' the cat outta the bag is a whole lot easier than puttin' it back. -- Unkown
