Why Siddhi is becoming Mahan?

Why Siddhi is not telling Kunal about Richa's deal..now court given her bail from jail..toh kyun woh Kunal ko nehi bata rahi he..kya woh soch rahi he Kunal aur Richa husband wife hai..agar ha..toh main chahti hu ki woh clues dunde about Kunal just as Kunal did..phir toh use pata chal jayega ki Richa Kunal ki patni nehi..then she can tell the truth..Why SIddhi is not visiting Chopra house or else she is now powerful she can find clues easily..
