I think... Vanraj has narcissistic traits, Anupmaa is mainly delusional and Anuj suffers from grandiosity.
At this point, Vanraj seems more reasonable than Anuj & Anupama duo.
Vanraj attacks who he finds useless to him/who threatens his ego/position. And he do it directly.
And Anupama loves her abusers and always trying to play "God" so that she can be loved/worshipped by her abusers. And for that to happen, she is willing to do anything. Agar CA ki jaam bhi chali Jaye to thik. Wo Summer ko etna jaldi bhul gai.
Waise bhi Shah House ke jyadatar Drame se wo Bahar Raha hai. Uske Karan sirf ek drama hua aur logo ne use abuse karna shuru kar diya! He was simply fed up of being doormat like his mother.
Then Anuj is simply beemar and calls his beemari "love." He lives in a delusional world. In his world, he is "best Bhai/Pati/beta/Insaan/Pita/Businessman."
But he has done nothing to earn that.
Birth mother ne paida karke abondan kar diya. Father ki responsibility ka to dikhaya nahi. Foster parents ne adopt kiya par jaldi hi mar gaye. He had unhealthy one sided crush towards Anupamaa which he was not able to let go for 26 years (clearly indicates a psychological problem). And then he got lucky! He adopted a child. Offered Sun and moon to her. But he gets nothing from Anupamaa. And in return he too neglects CA.
Oh haan.. He had a sister. Jiski usne life barbaad ki aur uska dhyaan bhi nahi rakha. Aur jaydaad ka uska hissa bhi hadap gaya. Phone karke puchta bhi nahi ki kaisi ho. Apne much older GK (wo mere Maa Pita dono hain) ko puchta nahi. Haan, sabko abuse karne wali aur beta Obsessed "Baa" uski maa hain. Aur good for nothing Baapuji uske pita hain. Anupamaa ke nalayak bachho ka buddy hai.
Par apni Gareeb Saas Kanta ka haal chal puchne, unhe jabki jarurat hai iski, par unki sahayata karne ka wakt/mood nahi hai Anuj Devta ke paas. Apne brother-in-law aur uske baccho par pyar lutate to dekha nahi. Jabki unka wo Uncle hai.
Ab MD ko abuse karwayega kyonki iske liye uske paas "righteous" reason bhi hai aur ant me use hi vriddharasham bhej dega kyonki khud hi yu hi Old age home ka concept to dikhayenge nahi.
He had one real pain... That he was "Anaath" and suffered childhood trauma. But he was fortunate enough to get very good chance at life which most children with biological parents don't get. Instead of taking therapy he is repeating the same cycle with CA. He married a woman who has God Complex so big that she could go any length to save her abusers no matter what the price is.
[Note: I am not suggesting they have disorder. Which is totally different thing. That's why I am not running a diagnosis. I merely pointing out their main character traits.]
