Why do women degrade themselves for other women

Jasmine and Matthew's engagement runs into a roadblock when Matthew's sister, Chelsea, attempts suicide over the pressure of their family demanding her to contribute towards Jasmine's sizable betrothal gift. Upon arrival at the hospital, Jasmine inadvertently overheard the family grousing about her insistence on the large gift. Taking a strong stand, Jasmine clarified her contributions towards the new house they bought and emphasized her right to expect a betrothal gift. Meeting Chelsea privately, Jasmine empathized with her situation but firmly refused to waive the betrothal gift. Realizing Matthew couldn't break free from his family's exploitative behaviors, Jasmine decided to end their relationship.
