A clarification about the story

I do not understand one thing here... how r they blaming bondita for all of these mishaps between the families. Wasn't the poor girl in London at that time?I was wondering what has bondita done to kaka sasurji for him to hate her like this...

Wasn't it anirudh only who took her away from the marriage to the psycho guy...n left her in London...??

Trilochan ego is hurted deeply after all the riots and decided not to maintain any contact with Bondita. 'Our of sight..out of mind..' this is applicable to him now. He is thinking that Bondita has changed after becoming barrister. He doesn't remember her qualities at all. Now she is framed in such a situation that proofs are showing that she is guilty. Anirudh also kept silent because of his desparate conditions ( Due to his father health, orphan kids and Tulsipur people belief). So everyone are raising the voice taking Anirudh situation as advantage. Trilochan don't want to take any risk by maintaining contact with Bondita.
