I donot think it should be like that of course pratigya will be thrown by krishna again too it will be insulting for her. so krishna has to go because it is his mother problem. pratigya didnot left the house she was being thrown out. once lady is being thrown out it is husband responsibilty to bring her back with his love and after all misunderstanding got cleared. even table being turned what so ever last time happens
pratigya did not love krishana at first place. he started love with her he is the one who goes after her. other wise she will be in good house today well educsated family and well educated husband it is because of krishna she is in situation like that and his family is uneducated. so according to aaj ka samaj nari pradan hai to krishna turn to bring her back. may be aaj uski shaadi kisi doc, laywer, good businessman (not sajjan type business man)se hui hoti agar krishna na hota she is educated today she can stand on her feet by working as manager in company.
so many case I have heard that first people got seperated because of some problem then they cannot live without each other they start dating each other like new couples again and get back together again after a while
problems are not always saas. there are so many other reason they get seperated even there is love marrige
so please donot insult her too much as show is about pratigya(nari ke hak). she is already been insulted by sajjan in hospital in front of eveybody then krishana not stopping her or let her go as he come back and say to dadi I donot need pratigya any more
thank you everybody
