Hi, there. The horse will show you what's not working, as she already has, according to your posts. So, you need to stop doing what doesn't work. If you approach her with pressure, with the direct-line human goal of CATCHING her, that intention/energy is all highly offensive to her, like you're a predator wanting to eat her for lunch. So, the whole idea of CATCHING must change into HALTERING, in your mind.
Then, you want HER to catch YOU! That's by your being ATTRACTIVE/NON-PREDATORY to her, whether it's by treats, or offering to scritch her itchy spots, or SOMETHING good happening for her when you're near. You want to even hold off on haltering her till she'll stand there while you play FRIENDLY game with her, for a bit, so that she'll always associate you with good things, & don't always halter her & put her to work, during the rest of your relationship. ASK her, rather than demand, like a partner, rather than a dictator.
Good luck, & there are many videos on youtube with free info on catching & rapport-building.
