thanks for all this advice, but we figured out our problem! He wasn't comfortable with me riding him because he was unsure if he was safe with what i was telling him to do. (THANK YOU TO MY TRAINER). so to fix it, i had to spend a lot of time with him on the ground before i got on. grooming him, leading him and then finally leading him around the ring at the walk and trot. when i got on, i talked to him and he moved off my leg.
to answer the questions:
-ive had him for one month and this has never happened before. i rode bymeyself when i tried him, and he was very responsive.
-he did this with loose rein, dropped reins, different bits, halter and lead rope, bareback and bridle less.
-i have been riding for 6 years, I'm comfortable walk trot canter jump(up to 3'6) and i don't have lots of experience riding green horses, but I've ridden them before. if a schoolmaster is a push button pony, I've never ridden one of them. Mostly i rode really lazy horses and the occasional crazy guy.
but thank you SOO much for trying to help with prince and i. It was really helpful!
