Acorn, that is hilarious!
One thing that a trainer told me once was to put the mare in a pen by herself and me be the one to feed and water her. For water I had to bring it every couple of hours and she had to drink the water out of the bucket that I was holding. If she didn't drink it, she had to wait until next time. After a week (I would have gone longer but something came up) she still didn't like me (we couldn't agree on anything it seemed), but I could walk out into her ten acre pasture (with 11 other horses) and catch her. So it did work. I also have used and really like the catch and groom, or catch and give a couple treats. Even just go out and catch her, pet her neck a couple times and then let her go.
I also find when I release my horse after a ride/work out, that he/she needs to wait to leave until I verbally release them. I will take the halter/bridle off, and have the horse stand with me until I tell them "off with you", or I walk away and leave. It seems to have helped with my gelding that I have now, he tends to be herd bound.
You'll have to tell us what you used and how it worked. Every horse is different, and in a different situation. For example, right now my horse runs in a 80-100 acre pasture, chasing him won't work. Believe me, I've tried chasing horses out there. LOL!
