I think Yashdeep still likes Gurpreet a lot. Amrita Rao shared my sentiments perfectly on the show. We all saw Yash as very happy and content while he was with Gurpreet. I think, to an extent, he was willing to fight for her and change his mother's point of view, but never got the opportunity. We saw an attempt from his side, when he had come to the Mammi Mehal to interact with the ladies. However, after what had happened on the show (i.e. Gurpreet yelling and getting very carried away), Yash backed off. Now, Yash got a lot of flak for doing so, but in all honesty, who is going to sit there and tolerate someone yelling at your mother. I also sympathized with his mother because, although she was wrong, she was totally cornered and insulted as well. She didn't like Gurpreet, that's fine, why force her. Everyone has their own tastes and opinions, and you can't force someone to like someone else.
However, despite Yash's cold and distant attitude towards Gurpreet, I still think he held feelings for her. That's quite apparent with his sudden change in attitude. He always looks so cold, emotionless, and almost robotic. He doesn't care about being on the show, or for any other girl for that matter. He had admitted that he looks at the rose Gurpreet gave him every morning. I think, to an extent, that he was being a jerk to Gurpreet intentionally, so that she would back off and it wouldn't give his mother an opportunity to insult her. I think he was trying to save her from future despair. But it's quite apparent that his head isn't coinciding with his heart, therefore, I think he should give his relationship another chance and work with her mother.
The questions is, will he?
P.S. I love Gurpreet. Her and Pooja are the best contenders for this show.
