I don't think much is going to change in this drama. I am pretty sure next week we will see Arjun coming home from auction to see his family preparing a party for Tanu's pregnancy. As usual Sujatha will emotionally blackmail him by saying look how happy your family is, at least for your family's happiness and izzat make the pregnancy happen for real".
And Arjun who doesn't have a mind of his own will sleep with Tanu. Poorvi who will somehow end up as the event manager of Tanu's baby showers will hate Arjun even more. Viraj may come to know about Arjun - Poorvi relationship and how Arjun ditched Poorvi in the 11th hour, will use Poorvi to extract revenge on Poorvi.
I have summed up 2 months story in 2 paragraphs.
With so much negativity going on, with Tanu, Virah, Bacha Singh family all strong opponents of Arjun Poorvi love, I don't have much hope of seeing Arjun Poorvi together and their love and chemistry being rekindled.
With the entry for Viraj guy, with Tanu spreading false rumours about her pregnancy, with Poorvi determined to take revenge from Arjun, and Arjun adamant to make Poorvi hate him, I am pretty sure there is more pain in store in this drama.
Arjun and Poorvi will only be going to be pulled further apart, unless entry of Viraj guy is like a wakeup call for Arjun.
It would have been better that Arjun was not married to Tanu and he& Poorvi were still together, and they faced this Viraj guy and Tanu together.
Wouldn't it be better if Poorvi somehow gets a job in Arjun's office and even though she hates Arjun out of desperation is prepared to work with him. (Wishful thinking!!!)
Another wishful thinking is Arjun refuses to be any part of Tanu's pregnancy and lets her deal with the situation herself. He sleeping with Tanu is the ultimate betrayal of the vows he took with Poorvi when he got married to her.
Arjun sleeping with Tanu will be like putting the final nail to YDSRH's coffin box at least for me.
