One of my cousin brother was in a relationship with a girl for 3 months, when girl asked him about marriage he told her that he will speak to the family and confirm her, our family denied about intercaste marriage and when he conveyed the same to her she started threating him and mentally harrasinh him that she will commit sucide, she is continuosly calling him when he ignores his call and always threating him that she will die.
Please guide me what can we do in this case.
