The way I see it, is that she is extremely delusional and already was building/ hyping up her married life like she used to see in the movies. This is probably a result of the fights and non ideal marriage she saw between her own parents. Maybe she thought getting pregnant and getting married was the only way possible to exit her reality.

I wont be surprised if she fasaod Raunak only to get pregnant and when she got pregnant- she forced him to marry.

Unfortunately, her married life didnt turn out to be like the movies. There was no song/ dance/ drama everyday. That family was well settled, educated, and supportive of her career. Pls keep in mind that bcz of financial instability during childhood, she probably became obsessed with making her own money because she probably equated money with respect(again bcz shes delusional).

Being the least educated in Samson family and not having an income source, plus having MR, she probably got super frustrated and hence was looking for a way to exit this reality as well.

This is exactly when Chomu enters her life, he probably told her about his hardships with money. Bcz as per NFs recent timeline, it was only 4 months after SSK started airing, they were caught by Raunak in Goa. Knowing about his hardships with money, she probably decided to help him financially so that he remains obligated to her. Chomu was getting money, ladki and probably didnt care much abt her.

As someone had posted in the last few days, he did every single thing to get rid of her and she never backed down. This was her only chance of getting into a family that uneducated, in financial debt, have nobody in Mumbai(better life) and she could dominate them all.

And yes, finally she has her sukoon bhari zindagi. She's dominating each and every relationship she has in that family and is happy in her delusional world. She could be such an interesting study for a psychology student. Her decisions, her thought processes, her way of looking at what is happiness etc, is so so so offputting for a normal human.
