What is wrong with Chum, I will go back to my ex? Really

During Wkw she said "Mera 10 saal ka relationship hai jo 3 saal pehle khatam hua but I may go back to him" This is so wrong, then apne hopes kyu diye karanveer ko. She is saying that usne ye sab karanveer and shilpa ko bataya hai but it was many weeks ago almost 3rd week she said all this, after that she has also been showing interest in karanveer. If she wants to go back to someone then why hurt others plus would any guy patchup like this. All this is even disrespectful towards him too.
