Jo galti karta hai woh galti sehne wale seh zyada hurt hota hai
It just clicked so well with AR.
Riddhima knows she has that regret of not waiting a few more days. Just a FEW more days and she could have been with Armaan. It angers her but there is nothing she can do about it. Her frustration leads her to blame Armaan (though she is right on her side about the letter, it still does NOT justify her marrying someone else). Him leaving the letter was not the reason why she agreed to marry Sid.
She acts so cold towards him, lashes out at him when given the opportunity but thats only after Armaan has shaken her up a bit otherwise she doesn't dare to look in to his eyes. She KNOWS by hurting him she will hurt herself. Woh usse dard deti hai and then she runs away because she can't actually SEE him in pain. Strange na?? After she told him about her marriage, she walked away ASAP! Why?? Why couldn't you stay and see Armaan's state??
If people remember the dialologue Armaan said in the FE:
'Main jaanta hu ke jitna dard maine saha hai tumse door rehke, usse se kahi zyada dard tumhare dil mein hai'
That was the MOST calm I had seen her in ages. Isn't the dialogue true?? She does have a lot of pain in her heart and this pain has come from the lack of Armaan in her life. She needed someone to understand that she has suppressed all those feelings which have left her in this zombie-like state.
Riddhima said Mujhe bhi jeena nahi aata tha
Well Riddhima....are you alive at the moment?? Is this what you call LIVING?? If you've chosen to stick by your husband then be happy.
