I think that Archana should first get over the fear of losing Manav. It is this fear (apart from her love for him) that makes her forgive Manav easily every time. But then Archana is like this with everyone she loves be it manav, Sulochana or Varsha that she ends up looking foolish all the time.
It is not that she does not make mistakes but when her intentions are suspected, it hurts badly. Manav of all people should know by now that she is not the kind of person to throw an important file in with the "raddi". I only hope that this thought occurs to him when he calms down. Savita's recent unexplained behaviour should also alert him to the fact that something is wrong somewhere. But Arman is Arman , they think thro their heart!I really wish that Archana should somehow disappear from everyone's lives for some while so that her real worth comes into focus. And she gets the much-needed respite from day-to-day Khich-Khich!
