Well, it depends how they want to take this journey. I mean, she wasn't madly in love with Mandaar, was she? Actually, I have idea, she never talks about this. Let's assume for now that she wasn't. This means that she's not in that position where she can't give anyone else the place of her husband emotionally and physically. However, her total lack of trust in him and the fact that she doesn't respect him will get in the way of her being able to see that he really is her life partner in every sense and that she can actually consider building a beautiful future. Trust is hard to come by and easy to break, especially because of how ruthlessly Raghav did all that to her. Can she ever have faith in him? She's attracted to him, we know that, but the kind of deep intense love that Raghav is bound to feel for her, will she ever feel that way about him? Maybe not. There are many relationships where one partner loves the other far far more, and they find a way to make it work.
What I would hate the most, though is Pallavi accepting him and the marriage just for social regions or as a marriage of convenience, apni kismat ko maan lena kind of attitude. I think Raghav would prefer she hated him than her supposedly 'accepting' him because she has no other option. He would never want to be her last resort but first choice. Dekhte hain how realistic they want to make this.
So i totally agree. I dnt want pallu to accept her circumstance. And showing some restraint with raghav will be the right move but i think pallu needs to have a raghv moment. She will see his goodness and begin to melt towards him. She already trusts him to some extent. She feels relief when he comes to save hrr from goons . She knows he isnt a bad person. Hes just volatile and destructive. She needs to see thr better of him and once that happens i have no doubt that shell be able to develop feelings for him and eventually grow to trust him.
