@madhu bua has her own frustrations. I mean she too is full of bitterness because the choices she made would have been for others. She never had any life of her own. Mostly Shyam might have been responsible for it. But then as it is khoon a ristha like many woman she is tolerating it or shall I say since Suman is not kicking out Shyam she is tolerating it.
Every time she sees Shyam might be a reminder for her of the lost life she had. There is more to what Shyam might have done to Devaki.
And since Meher's choice ended in divorce she is more bitter as she needs to tolerate one more man who in her eyes is useless as he has also bought pain to her niece. But bua is not seeing the reason why Abeer is there. He is there to protect them from any harm from Pinky Dada. She is unable to see his scars. Reason when you are an extreme feminist you see things from only one POV. Men are wrong, they use woman.
And Meher who grew up in such a situation where she has not seen a good man as a role model or to have hope that men can be good also evaluated Abeer with the same parameters of her dad. One mistake everything ended.
Whereas Abeer has influence of good women as well as good men in his life. Madhavi, his friend Sasha, Nissar have been positive influence on him. That's why he is more balanced than Meher in terms of relation.
if Madhavi has been little more assertive with kuber on Abeer's talent he would have turned out much better.
