Ok Maddie, look you're not going to take a scrap of advice from anyone, that much is very clear. I've tried to support you but also give you an adult perspective on what's going on, and that's not good enough for you.
Would you prefer me to tell you that 'from the horses I've seen come back from trainers to their owners, they ALL act beautifully forever and every and pop rainbows and butterflies out of their bottoms when they gallop'. I myself have worked on horses for people who have asked me to do so, Have got those horses going softly under saddle and resolved the issues the owner was having. Then I'll go back and check up on them a couple of weeks later, and sure enough, I can see the problem starting all over again.
So Maddie, sorry but you're clearly not going to listen to anything anyone says, don't try to get me onside on facebook from now on, I only want to hear from you if you've actually begun to take on board some of what people have tried to help you with. I don't have the time to spend on a hopeless case, a young girl that wants help but doesn't know how to take it. Once you grow up a little, you'll realise just how you come across.
