Dumb Mihika , Ashok track is nonsense

Ashok himself wants to stop the marriage with Shagun and Mihika knows this. When he does that Shagun will know his true colors. Then what is the point of Mihika trying to expose Ashok infront of Shagun? . They are showing whatever nonsense in the name of drama .
And Mihika completely lost her mind. Does she think she can trap Ashok all by herself without anyone's help? She did not even try to warn Shagun about Ashok even once. On top of it she brought Ashok home for Karwachaut as Shagun is feeling bad. Nonsense. Is she so afraid she will lose Shagun's friendship if she does that. Mihir does not care about Shagun. What is this girl's problem?
Mihika should have heard Shagun when she said Ishita went to bachelor's party on her own as she seeks attention from men when confronted by Raman regarding assault on Ishita. It would have opened her temporarily blinded eyes.
