Very true but only problem is that right now there is no communication between them and these games will atleast establish some form of communication between them.
We all know this is for TRP's so I do get what you are saying below but I differ in my opinion of her approach and her handling of this situation from a undramatic POV
There IS communication, we do see them talk, argue and fight. He does not ignore and walk away from her, pretending she does not exist. Today for example he did stand in the room and argue with her. That is communication enough to lock the door and bar it with your body while you just state the truth to the man. No frills and flounces about it and doing a song and dance to get a response from him. If you really want to put him out of his misery and bring him back to life tell him all you did was a lie and that will be enough for the man.
She does not need him to be the 'Mere Shivvay', which is what she is aiming to make him before she tells him the truth. To wait till that happens is a cowards way out. She has admitted she made the mistake and her decision was wrong - now just stand in front of the man and say exactly the same thing, it is as simple as that because that is what he needs not your FNP games.
The day is not that far when she will break down and confess to him but how much she'll be able to confess I don't know. Him announcing his engagement to Ragini is I think just a way to see her reaction n her loyalty towards him but he doesn't know that Ragini is a psycho n he is inviting too much of Raita. Pinky's revelation will also come after Shivaay announces the engagement as she'll become even more overconfident n then might end up self confessing every sin of hers. Annika never knew what she means to Shivaay n neither did OmRu understand the depth of Shivaay's feelings. Here for once I don't blame Annika either as Shivaay always sided his Mom over her n never really gave her the right or importance that she is an integral part of family. But I am happy to see the realization has dawned upon Annika n she is ready to fight for her love. Also, OmRu n Jaanvi are backing her. OmRu had always shown to love n respect Shivaay but this is the first time they are fiercely protective towards him. Overall I feel that day isn't too far when entire truth will come out n just hope that Ragini doesn't create too much mess. I am still hoping that they are not divorced though as that would straighten lot of things between them.
