The bird with the broken neck is the symbol of such abuse.
The bird represented the woman's freedom and something she wanted to have one day. It was constantly in a cage, like she was in her house married to an abusive husband. Even though he was not physically abusive towards her, the mental abuse was unbearable which is why she killed him.
