why not payal?

It's obvious that Swayam was extremely jealous in todays episode but why that anger for Shubh? Why doesn't Swayam question Payal as to what the hell she is doing? It's not only in the serial, but I see this too often happening in real life as well. When one partner flirts with another, there is so much anger and resentment toward the innocent person, but very seldom does one blame their own partner for their behavior.
