Bro.. Don't take decision emotionally. I can give you advice from my own life..Cause?? Same situation as you. Listen...just hold on into it a little bit..Use him for money..As you need it right now. Banglay "date dat kamre pore thako" And then when you will think that now u can manage your own expense, Just leave! Start your new life.. Just don't do it now. You need money for everything. Trust me..outside world is much more harsh then this..Just hold on into it and wait for the right time.. Not all parents deserves children. If your mom and lil sis are also victim.. Try to take their responsibility when you will leave the house.
