the first thing you never do is beg. You never beg a horse for anything. Don't beg them to come, don't beg them to go, don't beg them to love you. Don't BEG them for anything. REQUEST it, then expect it. They will love you for that, in as much as a horse loves, because they know what to expect from you, and that you will be in charge.
Start with catching your hrose. If you walk out to see your horse and she chooses to move away from you, you make that choice a very uncomfortable one. Have you ever heard of "walking down a horse?" basically, you approach the horse, not stealthily, just normally and calmly , like you are going to walk up and pet her. If she turns away from you, then follow along behind her, and if she starts to really move away from you, then you take the whip or leadline and you swing it out at her and SEND her away. You make a commotion, behind her, such that she is startled and maybe she'll look back to see what it is. Likely , she'll run forward. If she does, you walk along behind her. But, if she turns back to face you, STOP. Stand there and see if she'll turn around and face you. You might even back up a step. The idea is if she looks at you and thinks about coming to you, you do nothing that would drive her away. But, if she chooses to leave you, you drive her a bit so she gets a bit uncomfortable, and then wait for a second to see if she'll change her mind, look at you and come to you.
