I'm not going to jump to any conclusions or make judgement. IMO, If you feel that you want to go one direction and this is not the horse to take you there, then you are better off selling and getting what you need. Obviously this is only a decision you can make yourself, but if you feel that both of you will benefit by parting ways, then go for it. I sold a horse a few years ago, he was fantastic at jumping and eventing, everybody who rode him fell in love with him. I was told I was mad for selling him, but he wasn't the right horse for me and I now have Bandit who suits me to a T. Decide whats right for you, sometimes you have to let them go in order to move forward.
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.
