Now he want me to come 2 bangalore due 2 family pressure. But he z stilk in said activity and i am frustrated by his sex addiction which is brutal as well as unnatural followed by beating n thrashing. Due to this only he compelled ne abortion as he could have... for months (doc proof available) For last 6 months he z fighting with me for shifting but neither me nor my child want to live with him.

Kindly suggest me procedure to get rid of him and get money for me n my child education n expenses.
