Your horse, your life.
But let me point out that more than anything, you were lucky.
While you may have a great thing going with this horse? She is still a horse, and the consequences of what you did? Could be a price you don't want to pay.
Case in point.
There is a woman, 50ish, who was a barrel racer in her teens. Had wonderful skills with horses, been raised around them and knew well what she was doing with them.
She too had a good relationship with her horse, would go out in pasture, climb up and just sit there. Nothing on horse, and nothing ever happened bad....until it did.
For whatever reason, that day the horse spooked and took off with others. The teen came off. She became a quadriplegic that day.
34 years of sitting in a wheelchair, having to wear diapers, having to be pushed around, lifted in and out of bed/chair/car. Having to have BM's dug out of her since so many of the meds she takes cause constipation, dealing with bedsores. Can't do one thing on her own.
I think of her when I see posts like yours...
You may always be lucky, and nothing bad will happen to you, but if it does? Will the chance you took be worth it? Somehow I doubt it.
Horses make me a better person.
