I don't think you know what "broke" means if you are worried about her "losing her spirit." Also, a truly finished horse is going to take a lot longer than a few months.
FWIW, I send young horses to a trainer for 120 days with a pro trainer, and they come home with the basics to go on and learn the specifics for their future job. They walk, jog, canter, can ride outside, move their bodies around, etc. They are still not ready for a beginner rider. They just have the foundation for the rest of their education.
