And if you think she may go further than you that also could mean you are not 100% confident of yourself when around her and the fellowship which comes from bonding isnt there.
I mean that the horses I have felt a bond with have always made me feel good about myself. Not in doubt and if I was in doubt i would ask on NR, as you have done.
When I say she'll go further than me I mean that in the jumping/cross country sense. I've reached the point in my life where I know there will come a point whereby I don't want to jump any higher. Flatwork and dressage will have no limit from me.
She does make me feel good about my riding ability as everytime I ride her I learn & improve. I think its basically that she's not affectionate
