Actually I have different take.
Anuj was always a giver in this relationship even as a friend as when he loves/cares for someone they come into his heart not only in his life/house.
There had been moments where he left out of her life and not being appreciated even as a business partner, friend, Bf and fiancee. He actually openly said about this during pregnancy wedding celebration, where he acknowledged he won't be a priority for her, he understands and it hurts him, she did acknowledge saying she will try balancing it.
Like said Anuj/Anu, never process anything as Anu was never given time and Anuj is scared of allowing feelings overwhelm him, he will allow himself to feel in a controlled manner. Both are always occupied, when individuals slow down mind in life, they think or remember or feel more without anything to distract them. So the guilt, helplessness and especially the burden of being taken care of overshadows the equality in their relationship which is heavy for him
He always acknowledge her as a human and checking on her. Remind me, she never assured him really, as she keeps running to SF, and no matter how strong their relationship is they need assurance once in a while which rarely happens, as her priorities are never solidified, as of yet. Bad writing as makers flip flop her while I feel she priorities Anuj/CA but makers.
This with Any/V inconsistent behavios, with physical boundaries need to be addressed, side hug is no biggie but in this case this couple should give high five or a small nod, Period. Him joining call is OTT, it was Maan moment, he already said h doesnt know what it means to be a grandfather.
This is an opportunity moment for Maan to really have heart to heart without Anu singing they need me song, and actually Listening to him, also Anuj need to stop go when u are called nonsense.
