I disagree to some but there is definitely a setup that looks like Meera might end up leaving Krish. But judging by that scenario a lot of things can go wrong. Lets see it through each character's perspective.

1. Only Desai opened up, Meera is still playing game as talked with Krish. She is obviously moved by Desai's confession of love and has soft feelings for him but she did not open how she is feeling about this affair. She is in a confused state where she ....

I believe we can all agree that Krish is a lost cause. As I mentioned in my previous post, he sends Meera to Desai, spies on them, satisfies himself, and then reverts to self-loathing. He is never going to change his ways. The reasons used in the now-deleted ending of the previous version to reunite Meera and Krish are already diluted. Additionally, he has been caught with the recording device and has been sleeping with Maithrei (who must be in cahoots with Desai). Desai will use this to his advantage to completely separate Krish and Meera. That's why I said the best Krish can hope for now is to return to the setup they had before he fell from the balcony.
On the other hand, everything is working in Desai's favor. In the last episode, Desai expressed his wish to include Krish in the mix as before. However, I believe this was his least favorable option, as at that time he wasn't aware of the recording device (which I believe he found later) and was also unaware that Krish was at home when he bedded Meera. This time too, Meera came to him with Krish’s approval. Once Desai finds out about the recording device, he will revert to his original plan—to have Meera all to himself. I am convinced that Desai doesn't have much love for Meera, but she is his most challenging conquest, and he wants to add her as a trophy. He now has Meera in his grasp, planning further encounters, and her husband by the neck. He will go for the kill and get Meera all to himself. Remember, he uses various tactics, either role-playing as Krish or lamenting as a grieving lover, to say “You are mine” or “I am yours” or “I love you,” thus planting these thoughts in her mind indirectly.
Meera is not without fault. She crossed the line when she confessed to Desai about having sex on a train with a complete stranger, which she hasn't confessed or confronted Krish about. Of all people, she confessed it to the person who is trying to win her over. If she didn't like Krish’s cuckold ways, she could have put a stop to it by refusing to participate in his fantasies, reforming him, or walking out. In fact, she was the one who had the most fun (other than the first encounter with Desai, where she was overwhelmed with grief, she enjoyed all other encounters with everyone, every time). If she truly loved Krish, she could have gotten him out of his fantasy (he changes his stance after every encounter, lamenting about losing his wife until the next time) and started a family—after all, she is approaching her mid-thirties.
Even in this episode, she gave herself to Desai completely and willingly. The once holy-and-for-Krish-only act of spitting in the mouth is now repeatedly offered to Desai. That intimate connection she had with Krish through this act is now freely shared with Desai. On top of that, she is planning to continue the relationship with Desai behind Krish’s back.
As the author confirmed, there won't be any fourth part. This is the end where Desai gets his trophy, Meera loses her identity and becomes satisfied as Mrs. Desai, and Krish—well, I don't know what to do with him.
