Put yourself in his shoes. The boy fails an exam and you are contemplating leaving him. Its pretty sad. If the tables were turned, you would want the support of the ones around you instead of looking for the door.
Have the courage to call a spade a spade. If your parents only agreed to marriage because he would have a degree from certain school and on the condition that you would live in a certain country then that is everything that is unholy and wrong about desi marriages these days. Setting materialistic expectations and demands.
I used to make fun of white folks - the day someone became jobless, the wife would take the B-line out the door very next day. I guess thats now true for desi girls too. whoopie.
