He need to leave anyone but he should have been with his wife kya is us time abhimanyu ko akshara k sath b hona chahiye tha thats what i said. Sorry she didn't run away she was thrown out how you expect her to go their after all what happened that no one will go their so only he had to do was when she called him he need to just talk to her keeping his anger aside that's what I said.
These points have been discussed countless times, but I can still reiterate for you. Yes, he and everyone accepts that he should have been with Ak and supported her too. But the situation was bad and his reactions are understandable. He got mad on white day, but for the phone calls he was shown not picking up or not listening cause his mother was in a critical condition and he was literally scared to lose even her after all of this.
At this point, Ak's duty as a wife was to not accept his stupid anger and sign those documents. To say that you are in anger and grief and we can talk when you have calmed down. To go to Goenkas house like he asked her to do and give them all some space. Abhi failed in his duty as a husband to support his wife and to ensure her well being. But Ak also failed in her duty as a wife by not supporting the family IN ANY WAY she can.
They didn't throw her out, he divorced her. She could have gone to Goenkas and he would have come to talk to her after a few days once things calmed down. Even if she was mad at him for what he did, she had no reason to go off alone like that. Even if she hated Abhi and didnt want to be with him anymore, she had no reason not to go back to Goenkas after finding out she is still pregnant. Her reasoning is off in everything she does and that is where she fails. Making stupid decisions.
