Generally speaking theres hardly ever any news about couples, unless they're in the same shows.. And there have hardly been any articles on Sargun and Ravi to begin with.
It doesn't mean they have split up.
Besides, not being rude or anything, but how comes you're so worried about their relationship?
P.S. As far as I know we are not allowed to discuss an actors personal life on the forum, as it has no relevance to the show.
