Agree with tiny that it's not a case of either/or - 'disobedient' just means the horse is not doing what you're asking for(& implies that he knows what you want & how to do it), whereas 'herdbound' is a possible reason for that disobedience. If he is herdbound, that basically means that he doesn't want to go away with you. Working out how you can change your relationship so he's happy to go with you/do as you ask should give you a different perspective & approach.
Agree thoroughly with Palomine, that first & foremost it sounds like it is YOU who needs some good training. I would find a good trainer/instructor to help you learn how to deal with & train horses - because every time you interact with him is training too. I would also start learning the theory of equine behaviour & training principles.

IMO it sounds like someone's taken you for a ride, taking your money to 'train' a horse for 30 days just for bridling & trailer loading, without bothering to teach you what to do/what you're doing wrong. One thing I think it sounds to me like you're doing wrong is getting confrontational & fighting with him.
The lip twitch worked the first few times and has since stopped working.
What on earth was that for?? Did you twitch him & then load him, so he was too preoccupied by the pain to think, or...?
