Wow! Your pup is pretty much owning you, Darlin'. You are going to have to re-group and start training in all areas. Just this act alone will help him learn your relationship - you are Owner and he is Dog. Sounds to me like a huge issue is he is not just protecting you from other people and dogs - he is guarding you - like you are his possesion.
There are many books out there on training. Start with potty training and teaching sit, stay. Those are huge.
