CVs, please do make up your mind
You have butchered the characters of Purvi and Arjun enough already. What is this about Purvi telling Onir there is a limit to their relationship? He is the guy she hopes to raise her child with, at least according to the dialogues yesterday. She expects to take and take from him, giving him what in return? Friendship? Even Arjun seems to have moved beyond that, he has given Ovi his baby.
Also, Onir was shown to share Purvi's bed, even if platonically, in Kolkata. What is this sudden bakwas about him sleeping on the floor then? Please do not butcher his character and make a sensible man into a Devdas. Him sleeping on the same bed will not make him less of a man (he has already proved his big-heartedness) or Purvi less of a sanskari (that has been thrown to the winds, in case you have forgotten!) where Arjun is concerned.
If the intent with the sudden change in script is to bring Arjun and Purvi together, you guys need to make sure to show Arjun did NOT father Ovi's baby. What is food for the goose, is food for the gander, if Purvi is supposedly maintaining the "pavitrata" of her rishtha with Arjun, he should be following the same. One set of rules for him even at Purvi's bidding to Arjun to give conjugal rights to Ovi will not fly, the pavitrata will be tainted forever.
Please have a rough framework for your story at least, do not test your viewers' patience further by letting the scripts dither this way and that like the tattered sails of a shipwrecked vessel on a stormy sea.
PS: Please do not bash Purvi or Onir or Arjun, this post is just a plea to the CVs to maintain some reasonableness in their plot.
