Aniruddh's tears when he saw Bondita dressing in British attire and now when he heard the principal complain of Bondita's lack of attention at school, proved that his abstention from Bondita is not fueled by Manorama's presence. He feels very deeply for educating her, but his unwanted attraction towards Manorama and Bondita's crazy emotional blackmail is sending him into a downward spiral.
First it was the dressup with the painful pins and heels, then the tattoo attempt and now the fast. She is already a huge concern for Aniruddh.
I have strong feeling that she will fail in school and lose a year will lead Aniruddh to either suffer a nervous breakdown and turn to alcoholism or maybe self-harm as his only mission in life is to educate her. Maybe then she will change her ways, or maybe not even then (thanks to Sampoo n KSG)
