If I was Zoya ...

She wanted to do that the same night they got back from the airport but it refused to come off her finger.

Agreed. Or slapped him. He truly crossed the limit today. No chance for her to explain, no trust in the girl whom he ran to the airport to stop. It's really disheartening to see. He accuses her and she does nothing. Really disappointing.

As per precap if zoya find out truth about blood sample change
Than after prooving that she should get the ring and throw on his face.
When he can't trust her it is useless to get married to such a fool.

sorry firstly i am a man secondly broke the enggagement and will be wait for a right life partner.

I will shout Asad Ahmed Khan Sahaab. shut the F***k up.

Honestly, if I was Zoya, I would have left him the day he arranged that meeting with Akram and nearly got me (Zoya) married to him. This is my realistic response, of course.
