Alu..there isn't one scene after dishas entry where Shiva has shown he doesn't want divorce..he has been mum abt everything related to ravis right as his wife..
Yea..personally I knw shiva wants ravi always..but onscreen from what they show us, it is not more visible.and his actions says he has resigned..
And ravis feelings are no more hidden..he knows it very well that she is jealous and what all. he is playing dumb if he can't understand that she too has feelings for him..
It's possible that he might be resigned to the situation Deeps, but today's dialogue of his says that he doesn't want the divorce, when he said "hua nahi hai aur shayad hoga bhi nahi"
Also I don't think he's playing dumb. He can see raavi's jealousy but probably still can't believe that she is jealous because she is having feelings for him.
This is just speculation, we need a monologue from him to know better
