why simran and Manas had fight?

Simran wanted Manas to accept Urmila. But Manas got involved with Ria. So she went to him and tried to talk to him about this. During their discussion on this..Manas comments that Simran was interfering in Abhi and Neha's life and she was acting as an other woman in their life. This remark made by Manas hurt simran and thus they got seperated. I hope i made some sense😊
