We all used to talk about how Shiva hides his pain, and has no one with whom he can share it during the first divorce sequence.
I think Raavi is just the same.
Where Shiva uses anger as a coping mechanism and doesn't move forward, Raavi uses optimism to push herself to make the best of a situation.
Most of Raavi's breakdown scenes have been in private, even a bit during the wedding (in the room). She holds her pain close to heart because she' not sure anyone cares. There is no safe place for her to cry it out, and be sure that someone will hold her after and so she holds it in.
So Raavi's intoxication allows her inhibitions to be lowered and ask the person responsible for her condition why she was treated so unjustly.
#JustAThought
Keeping all the venom Shiva is spitting these days aside, I think both of them are in quite similar situation. Both have turmoil going inside their head but have no one to share their pain.
They give everything to their relationship but in return both still there isn't a single person in their lives to whom they can share the tears. And I'm waiting for the day that both of them will become this person for each other❤️
While Shiva masks his pain with anger, Raavi chooses to vent it out alone or cover it up with smile and assuming good things.
PS all the above Said things do not apply to post embryo kaand Shiva, I still hate him and nothing can justify him at present
