Hi Kim, Welcome to the horse forum.
Let me ask you a question: Would you go out and buy an airplane and then expect to teach yourself how to fly it? That is what you are asking us here. You do not know what you do not know. There is no way you can teach a horse anything except how to misbehave and be spoiled when you do not even know where to start.
If you really wan to ride this horse, the only thing I can do in good conscience is to suggest you find a trainer that will let you hang around and watch the training process and will let you participate where he/she thinks you are able.
I know you do not want to get hurt and I know you do not want your horse to get very spoiled. So, someone is going to have to teach this horse that knows what they are doing and you can learn by watching.
And as far as this bonding crap -- horses operate strictly off of respect. Trust comes from you being a good strong leader that the horse has absolute respect for.
Good luck finding someone to help you that will let you help them.
