You got some very good feedback. Take what you want and leave the rest. But, I completely agree with Cherie on the subject of a bond. it is much overrated.
However, your horse will become more connected over time, and since you say you have not had her long, you should be more patient. Do YOU feed her? That is one way to really get your horse connected to you.
I find, that if a horse is happy to stand next to me, even if I never touch it at all, then I know that horse feels comfortable in my company. For a herd animal, knowing that he feels comfortable in your company is a very high compliment, indeed.
