Anger and abusive nature are two different things. Here the ML is torturing her in the name of fraud done by her family. His anger is unreasonable as the real culprit he still think she is innocent but she is the one who betray him. But he is punishing her sister for what she didn't do. She already told him that she is ready to go to jail but he didn't , later on inhuman activity like he is doing is totally out of the character.
She is saying to him to atleast give respect to her as she is the dil he himself accepted in front of darji. Angad has never respect her he almost thought she is a prostitute who wants to sleep with him or is after money. Will any woman accept such husband who question on her character?
What sympathize with Angad ?? He is a fool and superficial person who see beauty over brains ! Who weight everything on money and status ! She has the right to raise her voice and she is correct why to force her to do the rituals when nobody has accepted her.
Chill. It's your opinion and I shared mine. We watch the same show and each is entitled to take their view.
Sahiba was party to her family's fraud. She cannot deny her responsibility. Nor can she expect the Brar's to accept her without any repercussions.
And they are showing Angad as unreasonable and abusive so viewers will sympathise with the FL. Starving her, everyone ganging up on her and mistreating her is the only way they can get viewer's sympathy.
If anyone is to blame here it's Santosh and seerat. And Sahiba's father too as he too stayed quiet. So in my opinion, the whole family is fruad.
