*** Kujadosham(Manglik) always lead to wrong connection.You are still young age,Better way search suitable guy.Dont loos your life.
***as per Sanathana Hindu Dharama..Same Gotra will be treated as brothers and sisters.So you are trying to marry your Brother Itself.
Better way search for other Guy..
