OP, to treat the animal like a horse YOU must be mentally TOUGH. It means the horse does WHAT you want, WHEN you want, and if there is a hesitation, you find a way to MAKE it happen. We should not say "easy, honey darling precious horsey" as they trample us. Give that halter a snap and MOVE them off of you. They move one foot? make them put it back.
It is not as easy as that, but a start. Always remember we are predators, and they are PREY. Horses think everything is going to eat them, and we have to convince them otherwise, by being their leader, but that means NOT being afraid, and not talking down to them, and not rewarding them when they do not doing what we want, but teaching them what it IS we want.
Horses learn on the release, which is not the easiest concept, because it is backwards from us. When a horse does the correct thing, we have to have the timing to QUIT teaching right then, not ina little while.
We will TRY to help, but, as you can see, it is hard in real life, nearly impossible on the internet!
