Maybe Archana sending Purvi away intentionally

Archana does not know about Onir's changed behaviour and she still consider him nice man. Moreover Purvi told Archana that Onir accepted her knowing she was pregnent. Now Archana wants Purvi to go away and live a happy life with Onir as everyone else will take Ovi side only. Also as mother it would be difficult for her to choose one of her daughters.
