I don't get why no one brings up that fact that she's legally married to Raghav now, and even if Mandar wanted, he can't just "take her back" (Like why doesn't Raghav just say it?)
She married Raghav thinking and legally being a widow, so I don't think her marriage to him would be invalid.
Also, why is Mandar acting as if Pallavi is just some toy that he can "take back"? Why can't Pallavi or Raghav say that, "well you can't, she doesn't want to be your wife"... because Mandar is in a "delicate situation" ??!?!? Such bull, he already knows Pallavi is married to someone else and has moved on so I'm not sure what they're protecting him from??
