What is Roli thinking!

I am confused about how Roli thinks things are gonna go when Sid finds out she is sneaking out of the house in the middle of the night to get Veeru interested in her. She is not only lowering her moral standards but also breaking the trust of her family and is hurting Sid with her current behavior. I love RoSid together and their chemistry but what Roli is doing to Sid right now is unacceptable! Roli may not be betraying Sid completely but she has broken the sacred trust between them. Sid has been very understanding but in any marriage trust is a must to get through adversity and here Roli is trampling all over it.
