I think armaan's one and major mistake is he is not stopping ruhi from interfering as well as blaming abhira..
He is not giving her any hint,no clear road,he doesn't even know that she still wants to get back together becoz if any sane person tells other one ki we are not posiible they think that other person get the hint..
Ruhi ne use abhi directly kahan bola hai ki I am waiting for 1 year to get over,I know promo mein bola hai but in show Abhi tak nhi bola..
But yes he is not stopping ruhi from interfering in their marriage,he is not stopping her from jumping on abhira,she even publically rebukes her...but fir drama create karein isse..yeh tolerate ho jayega but if he gets a free pass than its difficult...
Baki his body language was entirely different in case of abhira-ruhi..
He gave ruhi his coat but when he saw abhira also feeling cold at placeof returning her duppata he made hee sit close to him...
Aise toh ruhi ko coat mein apne sath leke bhi baith sakta tha..
Giving her coat is not some kindof love between them,armaan shownto be a sensitive person......
