I don't think a bond is an amazing emotional connection. My idea of an actually acheivable bond is knowing each other inside and out so that your interaction becomes second nature. That's what I ahve/had with Wildey - but again, he is perfectly happy without me at the moment too!
That's what I have with my 23-yr old. My family's had him since before I was born, and I know him inside out. I understand and anticipate his reactions before he himself knows he's going to react in a certain way, I can ride him bridleless because I can trust he will not spook, and if he did, that he would listen to me, and I could know how to stop it. If we meet something on the trails (like a dirtbike) I know EXACTLY how he'll react to it and can adjust and comfort him in ways that only I can, because I know what he needs. It's second nature to give him an extra nudge and turn his nose inward at the arena gate because I know he wants to stop there. I KNOW him.
Do we have some majikal bond? Lol. Maybe if such a thing existed, then yes. But lilTango, you do not
need to have something like that with every horse. Arthur's the only horse I understand like that, and it's a "bond" out of respect, trust, and status symbols. He's a naturally dominant horse, but he KNOWS I'm the leader and what I say goes. He's come to accept it, so he listens.
Keep riding....there will be times when you'll need a horse of your own to comfort and support you, even if only you know he's supporting you.
