I think she's being kept forcibly or blackmailed and her husband is changistani. Or she's herself a Spy.
I hope she's positive and she and Arya get together
She didn't give me the vibe that she's being kept forcibly or under any blackmail . The way she lashed out against her fake husband ( who was Ananta posing ) it looked like she's all the powers. She didn't look helpless or afraid , just grossed out and angry.
Like literally behen kaunsa delulu wala pyaar 
especially viewers aren't dumb to figure out that real aryaman didn't stab ahana but it was a nakli one and this is just all attempts to whitewash him
Ise to Aryaman jaap se fursaat nei ! Behen ,tu rehene de ! Tujhse nehi hoga ! Tu Bharni to throne and responsibility de de aur khud jogaan ban ja ! Atleast she takes her job and her country seriously.
