Honestly Teji, Seema and Viraj are equally to be blamed in this entire mess..
Teji wasn't ready to divorce Viraj and there was no way he could live with her any longer..so he decided to move out..Selfish of him to not think about his son..yes but what makes it worse is that he didn't give any explanation of his actions, such a drastic one at that, to his own son..he was not a toddler at the time..he was old enough to understand and process things.. what's the point of sending him gifts etc later? an open discussion on the whole matter would've been much more appreciated..
Teji- she lost her husband but she still had a son.. I would not judge her at all for letting Viaan think his father abandoned them...He did! that's a fact..or for returning those gifts.. What I would judge her for is the way she treated her son.. If Viraj was an idiot, she could've insisted on having a family discussion and letting her kid what's happening.. and if that's expecting too much then be there for him like he was for her..
In one of the episodes we saw how Reet went into a depression, jealousy, insecurity and may be post partum challenges both mental and physical that got the better of her, so much so that she ignored her own new born baby.. it was scary to watch a mother zone out like that while her infant is lying there crying on the bed..
Viaan was not that young but going through so much emotionally but Teji was never there for him..and I can bet even now she would be the biggest road block in his life..
Seema -no words.. pathetic character ..don't wanna waste my two cents on her..praying her and Vanya to leave town asap
