Well it seemed weird before but now after today's episode its clear that these two don't have any life of their own at all and their main life purpose is being near Ram as much as possible.
Shashi definitely has been jealous of Ram and there is an unsaid competition between them especially from Shashi's side. Now that he has married Vedika that also seems like only for the sake of making Ram jealous, thats why he seem to leave no stone unturned to make Ram jealous. His actions are at a very weird level of competition, maybe we will know more backstory in upcoming episodes but he is the same guy who sent his wife to Ram for getting his younger brother married to Shivina but gets their pics clicked as well as if its for his sadistic pleasure. I don't even know why he was marrying Sid to Shivina and what motive he had, maybe to control more portions of Ram's business by hurting Shivina after her marriage to Sid. I think in Ram and Vedika separation main role us if Shashi only as it seems like he wants everything that Ram has. That is why he always flaunts Vedika infront of Ram becoz that's why he has married her.
Vedika on the other hand, completely lacks self respect. I dont think Vedika and Shashi's relationship is bad but its more like a formal business relationship. She knows very well that Shashi is just using her with everything related to Ram becoz she is a scapegoat who has lot of emotional power over Ram and Shashi can get whatever he wants from Ram through Vedika. But I don't know when we will get Ram to see this truth.....maybe Priya will. But Vedika is fine with her husband's actions becoz that gives her opportunity to be around Ram whenever possible as she still loves Ram.
But everything will change for these two when in their centre of universe- Ram's life, Priya will enter becoz she sees people clearly maybe too clearly at times and when Ram also starts to fall in love with Priya, Vedika will become dispensable in Shashi's life as she will hold power no longer on him as she used to.
Uffff waiting for that day when this Shashi and Vedika will pack up from Ram's life, courtesy to Priya.
