Good afternoon sir Before engagement the brides looks ok with spreads After engagement the photos were came our family members seen that she's eye has mild (meli kannu) and we asked that issue to bride and parents.they replied that we already intimated.after wards we asked some time and said willing to marry.then also they attacked on my family members and me.arranged meeting to solve issue then brides father said iam sorry plz get married I didn't involve in ur family matters including his daughter.then after wards we married.the brides father taken advantage that we didn't have any back ground.the bride didn't have any knowledge to take her own decisions.she always passes informations what happening in house.un necessarily he is involving in all matters by putting his daughter in front.she follows simply what his father says.brides father is a real estate broker he is so much egoist.when his ego hurts then again unnecessarily involves by putting his daughter in front and makes issue from 3 years.so we don't understand what to do? He takes advantage that we don't have any back ground and my parents are old aged.my wife didn't able to take own decisions.any problem simply she follows what his father says.plz give any suggestions or solutions for this type of problems
