you spotted rightly..Arohis questions till then were mere hone wala pati ke sath kya karrahi ho. She can't say I love abhi.them which abhi pushing her. So she can't speak and he too can't justify his act simply saying I love ak. Both were quiet struggling for answer. When Arohi asked you wanted my happiness but you snatched my abhi my abhimanyu he spoke rightly when am I your abhi or your abhimanyu..he never gave her the right .he is like a dog falling on others to not them to his side as he is full of Ak. His protective instinct for both. He won't let anyone near him nor her. He just wants them only. When Arohi said regarding sirats death and Abhis snatching Ak froze and can't talk .when that i hate you came out both opened mouths. Because that hate only she is taking these many years and ti stop it now..she will say next dint leave anything..we will have more questions nand answers no doubt..in a way abhira are wrong ..they let this illusionary.marriage come till now amd broke it by uniting or confessing .there is no option for them too. If not now it's never. Arohi will be a victim always getting sympathy though her intentions are bad .
Akshu doesn't need a saviour. She can save herself. Abhi just supported her when she frozen. This is what the girl always wanted some to hold her nothing much. Even in 1st tilak she spoke against aarohi. The girl just waits for the right time to speak.
If you see before anyone spoke aarohi and harsh started to speak playing victim card that's how real culprits act. If you have truth beside you then you speak when needed. If you see aarohi might be wrong she chose wrong words by saying my abhi but her questions were right. In a way akshu is with aarohi's fiance during wedding time so she can't justify herself for that.
When aarohi said I hate you she said enough that's her breaking point.
Akshu speaks less but the girl knows when to speak what to speak and how to shut everyone mouth with one sentence. We just need to wait and watch.
