I agree that the golden rule is "don't air your dirty laundry in public", but I can also see why that's very often difficult to follow.
It's hard to hide your hurt or anger, especially if it runs THAT deep. I can see why Raghav is unable to cover his ghussa in public, not saying he can't do better, but he's simply expressing how he feels in his heart. He doesn't know how to behave any differently, dunyadaari isse nahi aati. If he really cared to fit in the world around him, he wouldn't be in Sanki's bad books and nor would his sister detest him. He wears his heart on his sleeves, as much as he tries to show otherwise, and I think that paired with his temper always puts him at a disadvantage with his loved ones.
Also, if roles were reversed, I don't think Pallavi would hide her hurt or anger either. We've seen her lash out at Raghav on multiple occasions without caring for the time or place. She's embarrassed him as much as he's embarrassed her in today's episode (haven't watched it yet, going off of forum updates) so I would hope she understands why he's unable to put a veil over his feelings.
All that said and done, what their marriage is greatly lacking right now is communication. They were phenomenal at it before their confession, but iss ILY ne toh inki shaadi shuda zindagi ki samjho jaan hi le li!
Completely agree with this…and the hurt is deep when it’s caused by our own and leaves nothing but regrets…he got ditched by his own sister and he knows that she is still going to be the one to suffer either way…when Sunny faces the consequences of his evilness and /or when she gets to know Sunny’s reality…and he feels helpless coz he knows he won’t be able to do anything about it…and the disappointment is directed towards Pallavi coz he thinks somewhere her naive nature is responsible for what happened…at least that’s how Keerthi made it look like…
Apart from lack of proper communication I also feel that with their extreme love for each other they unintentionally take each other for granted..
