One Of my friend got trapped in relationship with married man who told her that he was not having anymore relation with his existing wife . After being physical once , that man started avoiding my friend . Seeing his changed colors , my friend did some inquiry about him and came to know that he was having another affair with married women since 10 years who lived in chennai . My friend contacted that women to ask about the truth . First that women listened her calmly and also shared that she was also in relationship with that man . But suddenly after having some discussion with him , she also changed and started abusing my friend as a "dhandewali" . She daly sends her messages that she will come to her house and will insult her in front of family members & neighbors and will prove that my friend is Prostitute . She sends her threatening messages using very vulgar language and abuses her family . That man is not paying attention to my friend and only listenes his 10 years old friend .My friend got so scared of her that she went to his house and told everything to his wife . But still that lady abuses her sends her threatening messages . Can you please tell what can be done in this . Can my friend file a case against that man and this woman ? That man has ditched her , develoved relationship with her and left her and now wants to be with her wife . My friends life is ruined . Please tell if any legal action can be taken ....
