I started watching this show recently and caught with all the episodes. Preeti coming to ‘rescue’ KT is inline with her character. She is the same women who kept maun wrat ( I am still confused as to how his son didn’t know she could speak and kept maun wrat!! And his OTT reaction to her speaking! But I digress)
When KT was saying you don’t have to worry about me and started giving all the scenarios one by one about how it go real bad for him I knew she would agree to marry him. The argument that probably pushed her to go ahead with the decision was not his apology imo but him saying he had gone into depression for 3 years. Of course the apology would give her the strength to make the decision in that her marrying would be her decision.
Preeti is not kusum who also lost her husband but has his love and good memories which keeps her secured and confident. Her son treats her well and she is the matriarch of the family. Preeti is still learning and she would need kusum’s support always and she also needs KT to fill the emptiness she faced all her life. Everyone deserves to be loved and KTs statement probably made her want to give a chance to be open to such love. But without KT’s giving her a proper reason to marry she would/could have never taken the step. She needs to rationalize her attraction to him. She is very traditional and to fall for another man is unthinkable for her yet she was falling hard for him. She does not openly accept it of course.
any other scenario where her falling in love and then getting married would have been totally out of character. She is not strong ...not yet.
KT clearly did not want to let go of her and this was his way of holding on to her. They both need each other.
