Everyone knows how marriages are done in real life. Marriage can never be done like a blind date as they show in ITV, a marriage requires lots of thoughts, decision making, emotional investment, discussions with family and what not. Even in arrange marriages couple gets emotionally involved with each other during planning phase only, the effect is such.In our society and whole world Marrying someone is a much bigger thing than sleeping with someone without marriage( definitely being physical when you are in love is not wrong ,but marriage definitely brings much more emotions in the relationship)
There are many people with chronic illness or disability who marry just for love even if they know that they can't ever consummate . Marriage is that pure bond made by society which is revered all over the world.
Now coming to V-P equation, for me consummation isn't relevant at all, Virat is already much more invested with Pakhi by just marrying her. whatever he has done for her in all these years post Sairat wedding, shows his loyalty, trust and devotion towards her. They lived the surrogacy journey like Husband-wife, he delivered the baby himself, he trusted her more than his wife when Sai stated the facts, he barred his own wife from fetus Vinu when P blackmailed to leave , on the other hand when Sai did the same after proving P's crimes , he acted like a beast with her. This all shows that Virat was practicing emotional infidelity since always, Sai was just an object to satisfy his ego. Virat has crossed all boundaries much before marrying P, by marrying her he has only made their illicit relationship legal. Consumation shouldn't bother anyone of us now . What should bother us that how badly they are going to abuse Sai in coming days, as she has literally no one but only Savi at her side.
