In purpose

What if Sid in purposefully makes DurNi MU him to keep them protected. Sid would rather have his family hate him than have any harm come to them. From the letter it is that Roshni can be harmed...but if Roshni truly knows her Sid n if DD has truly come to know her jamai then both will realize that he is hiding something.

they can show this too... lets see what happens.. super excited! :)
