Is Sid confused???

Guys, in the last few episodes we saw that Sid was trying to influence Riddhima to take their relationship to the next level.

First, he asked her that, "Tumhe nehin lagta ki hume humaari relationship ko aage barhana chaiye? Tum samajhrahi ho naa mein kya keh rahi hoon?"

Then he danced with Riddhima (in which song we all know- Papa jag jayega) and gifted her a nightdress. Then Riddhima answered Sid that she needs time.

Then on Riddhima's birthday night Sid again said her, "Tum mujhe aisa kuch karke dikhao taaki mujhe yaakin ho jaaye ki tum sirf meri ho."

Then Riddhima came in front of him to go in the next level of their relationship wearing the night dress to make him believe that she's only his. Then what Sid did?

He said that, "Tumhe mujhe proof karne ke liye yeh saab kuch karneki koi zaroorat nahin hain."

This statement is totally contradictory to his previous activities.

Then my question is, what she has to do to prove that she's only his?

I won't be surprised if something would happen between them as Sid wanted to go in the next level.

But all of a sudden he changed his mind, but why????
