If you don't trust a person why commit yourself to him for life? she should give the man some credit, they have been friends for a long time , and right now Dhani and Vips weren't even on good terms, so how can she believe it right away that the pic meant something was going on between the too, in the pic Viplav looks sick with worry.taniya has no trust on viplav ... remember how restless she was when she came to know viplav spent a night with a girl , only after knowing it was dhaani she was cooled ... but tanya not trusting viplav is also justified since vip was never serious about their relationship ,still she never wanted to clarify what vip feels about her , may be somewhere she had the fear vip may refuse to marry her ... so i quite justify her reaction on seeing viplav with dhaani in a compromising state...
