And this man is someone that doesn't respects a woman or listens to advice. On the other hand she's finding it difficult to leave the relationship, and the only way to ease her pain is to pour out the tears.
Emotional trauma such as rape, sexual harassment to a woman that has never met a man can also make a woman to cry. Because the memory will continue playing in her head.
