That was an eye opener for him. He realised that she had reached a point where she has given up on him. Like she has herself told him k manaungi but agar na manay tou kya kar saktay hain. So he realised that he has to take the first step as Sana will not come back. And if he had no feelings for her, he would have not done that. But he is more afraid of losing her than she is of him. She knows he will be always hers and I guess now Sid has also realised that she is not going anywhere
totally agree after this both of them became more equal in the relationship stakes .. one fought the other made up .. he came after her after the press conference.. even Vishal going away .. and she consoled him in Teri shakal pe pyar ata hai ..After paras got saved ..
