Re: Rishta got broken one week before the wedding.
That was a tough read ( reading roman urdu without any gaps) but woo hoo i managed it!
Ok this situation is very tough and very unfair. I think you need to explain to your parents that you are sealing a bond in the eyes of God, its the same God for everyone, it doesnt matter what type of denomination you are.
Tell him that this is what will make you happy, and his family are willing to come to compromise.
If your closer to your mother then explain to her first maybe!
Are you sure there are no other issues? because this seems to have spiraled out of control! especially as your father knew before hand of the different denominations you were from!
