raunak and kasturi

Hi guys, i missed alot of epeisodes of Kasturi, well not exactly alot but a few episodes of it. This is what i know so far, Kasturi engagement with Raunak.

But do they get married? im sure robbie finds out that kasturi wasn't bad. I s it true raunak died, who and how he got killed?

Is kasturi married to robbie now? Why did she married robbie, for revenge or because she loves him? please help.
