trhere's many hints in the wedding dialogue:
- dadi said : you will regret your decision in the near future
- nani told him to be sure to never hurt khushi
- arnav told to khushi: i told you tha i can't live without you
- anjali said to shyam: arnav and khushi' relation isn't that weak
- when manorama said to khushi that arnav happiness is over all for her, khushi get a little silent and worry
So shyam witnessed all this hints and i think his next plan is to play on all theses words and wishes.
