If all the rumours that Shiv is in love with Ipshita are to be believed, I find his behaviour with Ipshi very strange. I do not recall a single scene which even showed a slightest indication that he had feelings for her. He does'nt smile at her. He does'nt talk to her unless needed. He does'nt look her in the eye when he speaks to her. He keeps referring to the portrait girl as the girl he loves even to her. He blatantly admits that he misses Gauri. He has no feeling of guilt when he looks at her (After all is he not supposed to be hiding their affair?)
Contrast this with his attitude towards Gauri. He holds her possessively. He gazes into her eyes intently when he speaks to her and even in other moments when she is in his arms. Although his looks are laced with sadness for what he had done to her, they seem to convey more than pathos. He feels anxiety and pain whenever Gauri is in physical or emotional pain.
Well if after all this they (the creatives) would like us to believe that Shiv loves Ipshi and only CARES for Gauri, they really have a funny way of showing it.
