Purvi leaving and the family.

So the leap has happen in Pavitra rishta. what i can't understand about Purvi leaving home is that Archana doesnt know where her daughter is. its ok and understandable if she wanted to leave home with the circumstances surrounding her but at least Archana should"ve ask Purvi to contact her when she found a place of settlement. its so unlike Archana to let Purvi leave home all by herself. I don't like the character of the new Archana (since she got back Manav). The old Archana would've fought for Purvi or try find a solution for her daughter. Manav promised that he would be there for Purvi but yet he has remain silent when she is being treated unfairly. The main point though is that i think Archana should be keeping contact with purvi. after all it does reveal in the show she has a cell phone. I also think that Mnav could've arranged a place where Purvi is safe and secure and let her stay there, of course it must be far from where the family is.
