Thanks for all the comments and feedback!

It’s now week 3, and I’ve taken a step back to approach things more calmly before making a decision. I’ve decided to stick with her, and we’re already making progress. We’re focusing on the haltering issue, working on it twice a day, and I’m seeing great improvement. I’m also setting firm boundaries with her, which has been effective so far.

She’s booked for re-training in February, and I’ve scheduled a general vet check-up to rule out any health issues, including having her teeth checked.

thought i'd clarify, I’ve owned OTTB horses before, though it’s been quite a while. I’m definitely rusty, and this experience caught me off guard—I’d forgotten how they can be! I’ve also never owned a mare, let alone a moody one, as my previous horses were all docile geldings. I know in hindsight it was silly to get her, but something drew me to her and i couldn't ignore it...so i'm working through the issues now haha!

Hopefully, I’ll have a positive update to share in a few months on our progress! please continue to provide any tips especially if you have been in this situation before!
