In which case I hope Sid's dad (and at this point the only person sid can rely on) will tell Bablu chacha, who will confide in nanima or maybe even dd seeing sid's state. Then all the family will work together to bring Roshni to Sid to help him get out of the cycle of depression.
On a side note I hope sid and mr.khurana go behind Simran's back and transfer all the property back on DD's name so that when the time comes and DD/roshni forgive Sid, they wont have to deal with psycho obsessive mother. I also hope kritika (no matter how horrible she is) realizes how much of a jerk rajveer is and teams up with samaira to teach him a lesson! đĄ
