Hope? Of course you can.
All you have to do is realize his power is all psychological and isn't actually real anyway. His power is the power one has over a child who is dependent on him. His power lies in you still feeling like that child.
But you are not. You are an adult with the free will to choose the path you walk. You can choose to be his prisoner walking the path he wishes, or you can choose to walk your own.
Once you realize your own power you will be able to do anything, and all those things that seem to be blocking you from leaving will be no more than dust. You will see that he is no more than a criminal who deserves the contempt of society. He is nothing.
Remember Natascha Duschamp? After ten years of captivity one afternoon she realized she could simply 'walk away.' And she did. And as soon as her captor realized he no longer had power over her he gave up the game. Without her belief that he had control he had none.
Their power is an illusion. The only thing that makes it real is them making you believe that.
The tables can turn in an instant.
