As per Niroop breaking trust part- I feel there were mistakes from both sides. It was very evident to all of us that Niroop is not a trustworthy fellow going by his several dialogues and acts , I wonder why Priyanka was stuck with him and Abhishek. Infact she was staying away from Abhishek the first week but later fell for his spell too. This ' group' of theirs was very weak and insincere unlike previous BB groups. But these 3 were always together not ready to mingle with the rest which was obviously for some selfish reasons for each on of them I feel. They splitting up was only a matter of time; earlier the better for both IMO.
