Here is my suggestion Marriage is not simple You must think for long run especially you are getting marry with Muslim guy nothing personal but why can not he change his religion How can you say ALLA from HARE RAM HARE KRISHNA We never ask anyone to convert so why do they do? Would you want to hurt your mom who carried you in her for 9 months and fed you all this a that and this is what you want to give your parent in return. Would you forgive yourself if they have heartache. I hope and pray that will not happen After all of this if you think this is what you want to do WIsh you good luck
