Really hard to second guess this from an internet posting without any other information.
Clearly you don't trust the trainer or her methods. How and why did you select this trainer?
And what's your contract with her? Do you want to pull the horse out of there? Do you want to find another trainer? Do you get money back if you're not satisfied with the results?
If you've been guaranteed a ridable horse at the end of 60 days, my concern would be that the trainer would be tempted to push the horse too fast, not that the trainer would be going to slow.
I'm assuming you hired a trainer because you didn't feel you had the ability to break the horse to saddle yourself?
If this trainer was recommended to you, and you like the results she's achieved previously, take a deep breath, chill out, and let her do the job you hired her to do. There is probably a reason why she's approaching your horse this way. You might even consider asking *her* the reason why.
There's really only two choices here - trust this trainer, or find another one you can trust.
