Is there anyone who can help you hands on? It is a great experience breaking or training your own horse but if you are having troubles you really need a second set of hands and knowledge to help you.
Can you make a roundpen?
I honestly think though that if you really like the horse but he is giving you grief send him to an agistment/training centre or get a professional horse handler/trainer to show you and guide you. Some horses are easier to break than others but this one is not a project for the inexperienced to take on by themselves.
Also not having facilities or gear can be a hassle too. Keep us updated on how your going
