Jasper was my paint/Arabian gelding who I had to sell for a few reasons (mostly me not being able to pay for him). In the later months of my owning him, he got really, really nervous to the point where it made me nervous to ride him. He was fine on the ground, but as soon as I got in the saddle, he became really unsure of himself. In the indoor arena, he would spook at anything (literally), and when I tried to ride him outside, he would stop dead and not budge. I would try to get him to move forward, but I never pushed him too hard because I was afraid he would rear or something.
I know I'm a nervous rider and I wasn't helping him, but is there anything I could've done to help him get more confident?
