Kripa is the one who did not trust angad. To get revenge she even consumated her marriage with prithvi which was according to kripa was a MAJBOORI!!! If she can go this far and have a kid with prithvi then imagine what else she can do... she always dobted angad! FIRST MISHTY THEN SIMON!
WE are jumping to conclusions and blaming Angad that he's playing with Kripa just to get prateek back and that he's bad and all. but think of Angad's feelings as well... HE ALWAYS LOVED KRIPA, NEVER DOUBTED HER AND ALWAYS WANTED TO MAKE HER HAPPY!!! SHE EVEN WENT TO JAIL BECAUSE OF HER!
I agree that by breaking his engagement with Kanan isn't the right choice but what can he do.. he was in a big misunderstanding that Kripa didn't love him and now she moved on in life but the instant he found out that Kripa still loves him as much as he loves her, he immediately decided to get back together....
Nishant on the other hand is a nice guy, caring and sweeeet but he's just not meant for our kripa... Nishant can have kanan if he wants BUT
KRIPA ONLY BELONGS TO ANGAD AND ANGAD BELONGS TO KRIPA
