Sometimes, when an owner can't control the horse, or if there are some behavioral issues, "being mistreated" is often the easiest excuse. I have a horae right now that We raised who is so funny and spooky about things that I know if he went to someone that didn't know what theu were doing that would be what they would say about him. It is a very convenient excuse for horse owners to explain, rationalize, amd not fix a problem.
Whether or not she was, horses tend to have this great way of dealing with the past. They move on and live in the moment. Past memories may affect how she reacts to a situation, until she is shown another way.
What she needs is more confidence and she also needs to be more focused on you? Havibg another horse around while you are working is very distracting. I honestly would consider doing work in an arena or large area while another works a ways off(make sure you are both on the same page). The other person will do their own thing and you will work on keeping her attention on you amd the job, and build her confidence.
