This has a little bit of a story, but you can skip down to the main question if you want
I'm currently taking lessons for english riding. I've been taking lessons for only a few months, so I'm still a beginner.
Okay, so today I was at the barn, and I was helping my trainer with some work. I was supposed to have my lesson, but she had to do something else, so we rescheduled the lesson and she said I could ride the horse if I wanted, but she wouldn't be out there to teach me. I loved that idea - more riding time for me! (I get one lesson a week, usually). I tack up the horse and take him out to the ring, tighten up the girth, etc (the usual getting ready to ride in the ring stuff), and get the mounting stool. I put it beside him and start climbing, and put my foot in the stirrup. I was about to swing my other leg over, but he started walking forward. I stopped him, and got the stool ready again, and he starts walking again! I kept trying to mount him, but he would not stay put. I was holding his reins, and they were over his head like they were supposed to be, but I could not keep him from walking forward. There was only one other person in the ring. I was struggling with this horse for probably a good 10 minutes. She did not once offer to help, or give me any words of advice. I think it was pretty obvious that I was struggling. I kept having to turn him around and lead him back to the stool. Then she left. She just walked out the gate on the horse and I watched her ride down the side of the barn. I tried again and finally I got on the horse. He started walking even before I made sure I liked my stirrup length, or collected my reins.
This has never happened before. This is the horse I've ridden most often, and only one other day has he walked away from me, but it only happened twice (but then again, my trainer held his head after he did it the second time) on the one day. Today he did not seem like himself at all. I've ridden him with my trainer not in there, and with nobody else in there, no trouble. But today was the first time I've mounted without my trainer in there. I told her what happened, and she said she'd show me after I finished riding, but she never did. The rest of my riding time was short, and frustrating, but that's another rant.
~So, my question is, how can I get him to stay still while I'm mounting?
Do you have any advice about dealing with him when he's in a mood? Most of the time in my lessons, at first he's terrible, and then by the end it's like he's on autopilot, which is great for me. But then sometimes he's in a mood and fights me about everything. I learned at my last lesson that I am not in harmony with this horse. I thought I was, but apparently not. Do you have any advice for being in harmony with him?
