Agreed with the first response post.
The point of a trainer is for someone to be training you, not for you to be training their horses. You did nothing wrong by loving your horses and putting them first. I mean, sure, it's good to think about it from her perspective and walk around in her shoes, but there is no excuse for someone being disrespectful to you. Find a trainer who loves your horses and wants to see you succeed, and don't settle for anything less, even if it takes a couple tries. God bless :)
