I think Mishti's character is taking after kritika's of Koi Dil Mein Hai. 😕 In that show Kritika wants Samay for herself even Though he loves kajal and she even manages to marry him, but her own insecurities drive them apart.
I dont think Angad will leave Mishti when he will finds out that Kripa is innocent, bcoz basically Mishti did not malign Kripa and Angad would feel guilty about leaving her, but Mishti's insecurities about kripa might coz the breakup of their marriage!!!Angad will get tired of Mishti's jealous & suspicious nature and divorce her. This is what I think will happen😕
