That dumbo samar is giving divorce to dilkash as he thinks that she wants to marry his friend and dilkash instead of slap him, saying him to divorce her. She came to know that maira was poisoning her food to harm her child but she did not tell this fact to samar or his family.
😲 It is very complicated. She knows how madly he loves Maira, maybe she thinks that even if she tells him he won't believe her.
