What we know...

SidNi profess their love for each other and are ready to start over.

Sid sees DD in a state of panic and unable to take care of her family due to not being financially able.

Sid instantly makes the decision of doing what his "mom" had asked him to do.

He bids farewell to Roshni while Roshni is happy to know he and her will be together again. That was the last time he looked at her and held her.

Sid tells Simran that he is not happy with what she is asking him to do nor is he proud of himself. He is only doing this for his sasu-mom, because he can't see his sasural in devastation because of Simran's actions.

Sid and Roshni go to proceed with the divorce. Roshni tells the judge that she does not want a divorce whereas Sid says he wants a divorce without looking once at Roshni. They are granted divorce.

Roshni will demand answers from Sid but Sid will not be able to answer Roshni as he is hiding the real reason behind him wanting a divorce. Roshni then will tear the divorce papers because she does not accept the divorce.

Roshni and DD find out about getting their property and business back. Roshni will most likely realize that Sid had something to with it and even DD might realize it as well.

Sid drives off to let out his feelings. His anger, hurt, pain all will be let out.

Sid arrives home and tells Raj and the rest of the family that he divorced Roshni. Raj slaps him for leaving Roshni. Sid is heartbroken.

Roshni's dad comes into the picture. He has no memory. Roshni at first has no idea who he is. There is a party thrown at DD's original house. Sid is also present their. Roshni finds out at the party that her father is in fact not dead bt alive. When Sid intervenes, she tells him to back off from her family matters.

This is what we know as of now...unfortunately I found no clues regarding SidNi's relationship. I am constantly trying to dissect everything that we have seen or have been told thus far and find some hints regarding Sid and Roshni. How clever are the team of JR, they honestly make sure no one puts up anything relating to SidNi and what happens to them post divorce. What I did hear though from someone on twitter that she heard that there might be another leap in the show. I guess if there is one it might be a small leap like a month or two. I am aching to find out more about what happens to SidNi.
