Ego takes over so the concern for HS doesn't even come into the picture. They have sidelined his happiness from day 1.
well mini did try before going asking her babes to give her a parting hug once, asking her to speak to her once. And the letter she left for babes it was full of love for her. which mother would still be in ego and not try to reconcile with mini even after reading the letter. I think babita dint want to try. Mini door chali gai to gayi she dint even try to keep a connect with her over the phone or by video chats i think. And mini must have lived under the assumption that babes is still angry with me
