My Name is Maninder pal from Punjab. I am a software developer and was earning a good. my other brother is working in the fourth class category as an unregular employee in government. my parents always have a soft corner for him and to me nothing and even to our children also.. they love his kids, not mine ... I always help my father and give him money each month my father builds the first floor and asks me for money for help. i gave them money. then my other brother lived on the first floor and I started living with my parents all the house expensive i have to give 50% to him even the all relatives and all.. to another brother they did not take any money and always put the burden on me.. after my marriage things start badly to all people they say the first floor is for other brother and this portion is mine. but actually, when I ask they say we have a share in this place and your other brother also has a share. when I ask if you have shared in this floor and then must have shared in the above floor also just same for both sons.. but he fights me and then throw me out from home .. what should I do... I can not write all things that happen to me and my wife emotionally and physically ..
