pavitra rishta ending?

Is pavitra rights ending in 2/3wk

Probably not, because they have opened up so many things for them to show and how it all becomes better. These are the following reasons why Pavitra Rishta WILL NOT END in 2/3 weeks:
1} Archana and Manav's divorce (Which is probably the reason you think it will end when the divorce case is over)
2} Archana will have to win the hearts of the Deshmukh Family members and let them know the truth
3} Arjun and Purvi's wedding, which will not happen soon because Ovi will create problems
4} They have not yet discovered that Vishnu is Soham, and Varsha will create problems at first so they won't find out and then Soham not finding out that Manav and Archana are his actual parents.

So, I'm pretty sure that Pavitra Rishta will last for at least 300 more episodes.
