Sometimes we have to come to a decision about what is more important to us - the partnership we currently have, or progressing. Nobody can tell you what you need to do, but don't feel that you need to settle for what you currently have. If your dream is to move forward, maybe you need a new partner to bring you to the next level. It is never easy to sell a horse that you have a bond with, but sometimes allowing your current horse to move on, will enable you to develop a bond with a new horse who suits you better.
Stop for a minute, open your mind, learn. You may not agree with what I say, I may not agree with what you say but we will both learn something new.
