With got this picture from somewhere and it's emotional stirring. Many thoughts are flooding in my mind.
She has the key to save him and change their situation. Regardless of how they got in this predicament, she still holds the key. Now she could give him the key and "set him free" but she doesn't trust him. She thinks if he could get away by any means he would and leave her to die. But he wants to save her regardless of their situation. He will stretch himself far and thin in order to save her to have her to hold her. However he is powerless to change anything under his circumstance but he tried so much and unfortunately it will never be enough. Not enough to make her trust him and not enough to reach her. He would break his own chains if he could but he simply can't. And even though she is the one dying, she has to most power. She could save them both but she would die before she trust him. And he will eventually die without the key.
Why do people trust only family instead of their beloved one. People thought there's no conflict in between family but this thoughts will never be "applied" on their spouse. Many- money, privacy, secrets. I'm definitely not the one with this mindset. Family love you inevitably, that's an inevitability in the basis of consanguinity but whereby beloved one will not do you any harm without a basis of consanguinity. This point deserves special emphasis.
