Zoya's stubborn attitude and Aditya's small prank made her decide to marry Arshad.
In Thursday's episode, Aditya actually broke her stubbornness by making her realize what she is doing with her own life and with him. Even if she called Adi's love as paagalpan but his words had deeply affected her. His words had made her feel she shouldn't marry Arshad.
On the engagement day, she was looking for Aditya. She wanted Aditya to come to her home to convince her again to break the engagement and somewhere she was ready to do that. She did not even care for the fact that her abbu was ready to give his old ancestral ring to her to put on Arshad's finger and get engaged. Ancestral property are symbols of ones pride and heritage and Waseem was ready to let go off his pride and prestige for his daughter's future. But still when Zoya came to know of Adi's 'accident', she didn't care for her father's pride, her family's izzat, let go off his hand and crossed the threshold to reach Aditya. She told Waseem that Aditya needs her that's why she has to go. But actually she needed Aditya so she left.
When Zoya saw Adi unconscious, she told him she left her engagement to come to him. She said that to made Adi feel that even after his prank call mistake, she still trusts him so much that she left her engagement to come to him.
But when she realized Adi once again lied, this time her real trust on him broke. Last time Adi said his intention was not to harm Arshad which she even believed but this time Adi's prank broke not just her own trust but also made her to embarrass her family in front of everyone.
This time with her trust, Zoya also broke and the broken Zoya puts the ring on Arshad's finger in front of Aditya. The moment she put the ring, she became weak. It was more painful for her to take this step and she took it.
Today, we saw a completely weak and vulnerable Zoya who lost her voice, her identity and her confidence. People are taking her life's decisions on behalf of her and she is standing still helpless without opening her mouth. Today, she has become a lifeless person. She does what Waseem and Arshad tell her to do.
Somewhere her heart still needs Aditya and she is asking herself why she needs him.
At this stage only Adi can help her but not by trying to be her lover but by being her best friend. Only his friendship can make Zoya strong again and give her the will to accept her love as well as fight with Waseem and Arshad to fight for her love.
But will Aditya decide to be her best friend again? We will get to know that in upcoming episodes but today indeed Zoya ret ki tarah bikhar gayi hai.
