Hi Guys I have figured it out......
The thing is Aditya loved Bani's mother and therefore has always held a very soft spot for all the 3 girls.
Aditya was okay .........but in the intial episodes when Roshni came back, he overheard Jai's and Roshni's conversation and found out that Jai is the killer of his dearest Kiran ( Bani's Mom) therefore starts to hate Jai and decides to trouble him.
Soon in a couple of months .. when it is found that Jai didnt kill Bani's mom he will also come around.....
Guys this is the very reason that Aditya and Jigyasa broke up and that's why Jigs hates theses three sisters sooooo much.......
what do you guys think!....
tata,
