the reason anu become mad

I think ritesh will brain wash Robindo to gamble more,he will loose everything,there will be rift between 2 brothers,Robindo will be killed,blame will go on anu,he will go to jail,here everyone will turn their face from anu,they will become poor, to save the grace of family tani will get marry to ritesh in jail Anu will be tortured too much and he will get news of tani marrying to ritesh he will loss control over his mind and will become crazy.
option 2-after knowing tani got marry to ritesh and divorce anu he couldn't tolerated shock and try to commit suicide from the cliff then he will be saved and will become mental.

too much time will be needed for this track....

she is already married to Onu.
