Hannoveraner Wallach, angeritten

Gatsby is six years old (born 05/2017), broken in and only for experienced riders.
He is very sensitive and has a mind of his own. I would like an owner who is consistent and fair with him and has the self-confidence to give Gatsby security when he becomes insecure.
I can't give him the encouragement he probably needs. Over the past four years, I have tried many things and have outgrown myself, but now I have to admit to myself that this horse is too big for me. Gatsby is not a distress sale, he doesn't have to be sold immediately and at any price. I would like to find him a new home where he will receive lots of attention, will be encouraged and will get routine for life as a riding horse. He lives in an open stable with a paddock trail in a mixed herd of 15 horses and ponies, is high ranking and has 24h hay at his free disposal. Due to his sensitive stomach, I would also like him to have 24h hay in his new home and I think he would be a little less stressed in a herd of geldings only.
Under saddle, he has never yet bolted or climbed, but he tries to avoid difficult tasks and sometimes jumps, goes backwards or looks for something in the environment that he can get into. You then have to "assert" yourself confidently and give him security. As soon as he realizes that you mean business, he becomes cooperative again. We took part in a pole training course last summer, which he did really well and generally enjoys varied work.
We are regularly accompanied by our trainer with lessons. She is available for questions and reports, so I can put you in touch with her.

I could also imagine a swap with a reliable, sociable pony/horse or a mutual sale if everything fits.
