Abhimanyu and Sweety probably were getting somewhere before all this happened but they haven't reached the stage where they saw each other as life partners.
Sweety has no where to go now.She doesn't want to go back to Haweli and has no means to support herself so she may agree to a marriage of convenience with Abhimanyu.
Abhimanyu is lonely and was consciously or unconsciously looking for a partner.
If the marriage happens it is a compromise marriage for both of them.He will get a companion whose tastes are similar to his own and his daughter will get a mother figure.Alina stirred maternal instincts in Sweety and in that father daughter duo she probably saw a family that she could never have with Rituraj.
Ultimately it is not a bad deal for both.
Nimki right now wishes to fight her own battles on her own.I think she should be left alone to do that
Problem with Nimki is that she observes everyone and everything from her own POV and every other opinion and ideas therefore becomes irrelevant to her. How does she think of matching her with a man and expects everything to go well on it own ? For Sweety who has suffered an unhappy marriage is being pushed for another unhappy marriage. Wife beating and a womanising husband is not the only reason why a woman is unhappy in a marriage. Nimki still lives in her own lala land where husband is someone who will take care of his wife, buy her gifts, take her for dinner and perhaps click selfies. She still doesnt think beyond her filmy ideas.What worse is that Sweety was never told how Abhimanyu always liked her which even little Alina knows about.
I dont have much problem with Nimki here because she always was like that. What is wrong with Masi and Abhimanyu himself ? With Nimki around and fliritng all the time she wants Abhimanyu and Sweety to live like a regular couple ? What is with Abhimanyu ? Becuase Nimki rejected him he was obliged to accept Sweety out of the blue ? There were thousands of way to help Sweety without even marrying her.Frankly speaking, Sweety needed more time to overcome her divorce with Rituraj. Her husband was a scum yet she was in love with him at one point of time and had a relationship with him for quite a long time now. Right now she is just a confused soul and too much influenced with Nimki's krantikari ideas. she is not even ready for a relationship. At the end of the day she was first influenced by her father's way of looking things and now she is influenced by Nimki. Where is her own opinion ?
