Yes what Swarna told Ab is the truth. Every relationship has its boundaries and if you cross that boundary they end up in mess. But ab won't understand it as she is never receptive of knowledge. Her mama had taught her everything.
First and the foremost why ab allowed ar to partner ru, take care of ru. Ab has always been emotional fool for me when it comes to ar, but the intentions of ar doesn't seem good.
Ru has to be ab's responsibility. He can handle clients and meetings, and should not be around ru. Ab and ar not observing this rule are playing with ru's already frayed nerves, mood swings accompanied by cravings and loneliness.
Why ab wanted this babymoon if she was so concerned abt baby. She is not carrying baby, ru is. She will have cravings and everyone knows outside food need not be good for preggy woman. She craves for coffee and other food creates nausea for her. These are common pregnancy things.
I didn't feel anything for ab when ru burst out. Abhimaan have kept her in a cage with instructions not at all understanding the emotional upheaval she is undergoing.
Ar should be strictly kept away from taking care of ru in any condition. Ab or any other family member can take care of her. Otherwise as K predicted the consequences are not going to be good.
And in S4 marriage anyway has been a joke. From ru marrying ro to see ar, ab making a deal out of the marriage done by ak to Kiara trying to make Abhir jealous who is sleeping with Charu, and Charu going ard sleeping with Abhir who is married to Kiara and ar and abhir both oscillating between women and Ro running away, the relationships of s4 were open with no boundaries.
