Reasons why Eveline let go of the opportunity to escape:

Fear of the unknown:
Eveline is hesitant to leave her familiar surroundings and venture into the unknown. The thought of starting a new life in a foreign country without any guarantees of a better future fills her with anxiety and uncertainty.

Sense of duty:
Eveline feels a strong sense of duty towards her family, especially her father and younger siblings. She has been the primary caretaker since her mother's death and feels responsible for their well-being. Leaving them behind would mean abandoning her duties and betraying her family.

Guilt and obligation:
Eveline also carries a heavy burden of guilt for considering leaving her father and siblings behind. She feels obligated to stay and continue sacrificing her own happiness for the sake of her family, despite the toxic environment at home.

Emotional attachment:
Eveline is emotionally attached to her home, despite its shortcomings. The memories of her childhood, the familiar streets, and the people she knows provide her with a sense of comfort and belonging. The thought of leaving all of this behind is too overwhelming for her to bear.

Psychological barriers:
Eveline's past experiences, particularly her abusive relationship with her father and the death of her mother, have left deep psychological scars. These traumas have created barriers that prevent her from taking risks and seeking out a better life for herself.
In conclusion, Eveline's decision to let go of the opportunity to escape is influenced by a combination of fear, duty, guilt, emotional attachment, and psychological barriers. These factors weigh heavily on her mind and ultimately lead her to choose familiarity and security over the unknown future.
