Sid has started realizing that Roshni can't be happy with him. The way he is seeing things, there is no scope of Simran Roshni relation betterment. In this 3 months he will see Roshni suffering the taunts of Simran, RV and Kri and may feel bad for her. He knows Simran won't understand even if he or Raj tries, so he has given up on Simran😕 He is neither getting angry nor is happy with her😕 And he would not want Roshni to suffer there, when he is not able to do anything for her. On top of it Khurana patel rivalry is only increasing and if Roshni has to come to him, it should be against the wishes of DD. He wouldn't want Roshni - DD relations to be spoiled again.
And from Roshni's side there is a big communication problem. In 3months she will understand Sid is not bad, but will fail to convey that to him. When Roshni doesn't apologize nor convey her trust in Sid I'm sure Sid will think she is not happy with him. So, I think he will let her go after 3 months. And he would somehow convince Simran to give back the DD property b'coz he is divorcing Roshni. Sid would have forgiven her by that time but won't pursue her b'coz he won't be sure whether Roshni wants to live with him.😕 And Yash is there to complicate the things further.
So, a major drama will be there after 3 months. Roshni would want Sid to call her back, and she may not say anything till the last moment. But once she feel that Sid is not going to call her back she may break down and seeing her condition DD may help her go back to sid.
I don't know whether something would get resolved before the end of 3months. Even if some nok - jhoks and good moments may happen b/w SidNi in 3months, i think the final breaking point would come only after 3 months. Till that time I don't see neither Roshni nor Sid speaking their hearts out. 😕 There is big ego issues
