I have ridden all my life as a pleasure rider and happy hacker. I have had horses on and off, losing my last one 4 years ago to old age. I have had 4 horses through out my life, one being a younger one which I brought on but he was on loan. Since then I have been going for lessons so I can keep riding. I decided I wanted to own a horse again so i have purchased 6 year old gelding. I just wanted a horse to hack alone and maybe do a bit of jumping and low level competing if I wished, but mostly hacking. The one I purchased was suitable for hacking had done a bit of jumping which I was happy to bring on if I needed to. I have had him a few weeks, in the few weeks I have had him he bolted when we was hacking which resulted in me falling and hitting my head on the pavement and having stitches. I haven't been on him since as I have been recovering, however I have been every day spending time in the field poo picking and just grooming him etc. On Sunday I was in the field with my husband we was poo picking and he tried to nip and spin and kick me. My husband shouted no he stopped didn't think any more of it. Monday was doing my usual routine, was poo picking and he came up to me and started trying to nip and kick me. I was firm said no, but the more i told him off the more he did he and he just kept coming at me. I got out the field which in hindsight I maybe shouldn't o done, but i am still recovering from fall. Yesterday tried the same again but with my husband. He is fine at the gate but when we went down the field he did it again, even with my husband being there and he has no fear of him. Since the fall, I have gone in with confidence with him but now I am scared of him and he clearly knows it. I am told it could be because he isn't worked but I just don't understand why he is acting this way, I have never been aggressive towards him or wacked him. I am worried that I am going to bring out more bad behavioural problems. I am not the most experienced rider in the world but I am not a novice but i have absolutely no idea how to do deal with this. I don't know what to do with him in the field and my main hacking route is the way I went and I am worried that the next time I go that way he will react the same. I just don't have the time to do more schooling with him. Has any one ever been in a similar situation? My family are telling me not to give up on him however they are not the ones who have purchased him and spending time with him and riding him. I am trying to think of it as what is best for him and maybe that isn't me. I am sorry for the long message but any suggestions would be appreciated.
