So is Trupti really cheating on Sahil?

So is Trupti really cheating on Saahil? Or is it just another "money" issue? Seriously, how low can a woman stoop?
In a way I think its better if Trupti is cheating because that will at least give Saahil a reason to dump her for good!

(Seriously I find Sandeep Baswana soo cute, but the woman who plays Trupti looks like his aunt! They should at look at each other's age!)
