First thing to know about my aunt is that she has always had a fear of horses, but she never acts too scared around them. I know Comet can sense her fear though. Apparently when he first came out to the farm a few years ago he bit her as she tried to walk him. She tells me there was no warning (I know there must have been) and that she didn't do anything. That was where their relationship first went sour. Rather recently I walked Comet near her and when we got within 5 feet of her he leaned so far back he almost sat down. He definitely saw her standing there and agreed to go forward with me, so why did he react this way?
After this year of me working with him we've undoubtedly come a long way, but she still thinks he's dangerous. Now that my uncle has bought another horse that she trusts she is thinking of sending Comet down the road. Personally I think this is a horrible decision but I'm only 17 so my say only goes so far in this. It just seems a shame to send away a horse that I brought from not even letting us catch him to letting me saddle him (previously he was terrified) and get up on him. Plus, I just love the guy! He has never so much as even accidentally hurt me, but she thinks he's basically no good.
How could I help their relationship improve, and why does he "hate" her so much?
*she has never hurt him, so abuse is definitely not the issue here.
