I am by no means an expert here, but did watch my daughter interact with a “Nervous Nelly” for far longer than she should have (This horse is one who inherently gets her confidence from her rider, but was not originally crazy). Trainer inadvertently taught her that when something scares you it is best to explode. Stupid, trusting us. ssole trainer.
Anyway, my daughter tends to get nervous, but has always been a confident rider. First time dd got launched by panicking mare no big deal. Second time same thing. Third time dd started to get nervous when riding mare. Not visual to the human eye, but glaringly obvious to mare. DD was nervous, mare decided there was something to be nervous about. This got dd more nervous which told mare there was even MORE to be nervous about. Rinse, wring, repeat. DD quit that mare after 1 1/2 years with my blessing. DD expected something to go wrong every time she got on the mare. Mare reacted. After a time no matter how much my dd tried to “relax” and have only good expectations somewhere inside my dd was still expecting an explosion. Mare, being extremely sensitive/reactive and not having her own confidence just couldn’t hold it together for dd. DD finished out the year on her lazy *ss, been there done that “I like kids to ride me cause they don’t ask anything of me” paint gelding. He didn’t give a crap how nervous she was. He did what he did and never even thought about unloading her even when she was just about in tears.
Fast forward a few years mare came home and got to be a horse for a long while. I plan to hop on her this summer. I am a su*ky rider. DD is an awesome rider. BUT I don’t have nervousness issues. Mare can get her confidence from me. I won’t ask much of her, but she will feel safe.
I guess this is a long-winded, convoluted way of asking if you two are at a point where even though you think you are projecting a confident, no nonsense image to her, you are actually subconsciously sending her EEK vibes. Ask a confident horse person who has no history with this horse to take a shot at this problem. See what the horse does. You may be surprised.
*Not suggesting you can’t work with mare etc., just that this will give you more information on what you might be up against. Hopefully this makes even a little bit of sense.
