Malabika From Bengaluru want legal help in Divorce / Marriage

Respected Sir/ Madam,
This is to bring to your concern that I’m married to Mr. Arunabha Roy for the past 8 years now.We got married on 17th February,2012. I have a son of 3+ years old.
However, things were bitter from the very beginning. He used to physically n mentally torture me.
I did convey to his father but it was of no use. Now that last year only his father expired , he is troubling me all the more.
I consulted a counsellor at HAL police station but it was of no use.
The counsellor did rule out that he is suffering from bipolar disorder . She suggested me to take away my child and live seperately.
Sir/Madam, I’m an orphan and I have no one to support me .
Since I have no place to go, I’m not willing to take my son right now and more so I’m not working.
Sir/ Madam, I just want a divorce from him. I told him this many a times but he always breaks things and make fights with me whenever I speak about it .
Sir / Madam, know kindly help me. I don’t want to ruin my life .
I want to start fresh again so that the mistakes I made I want to learn from it.
Sir/ Madam, since I’m unemployed I may not be able to do the payment for this. But out of humanity kindly help me . I genuinely want someone to help me. Please save me.
