i personally dont want to give suggestion in such matter.  you got to think.  think about your future, career, parents.  and you are not sure if this gonna last, or are you?  do you really think he is the person you wanted all the life?  i am assuming you are an undergrad student, you got long way to go.  stay focused and do well, thats all i can say.  if someone ask me what is your personal choice, i would always say nepali girl who can understand my culture.  i dont need to spend time and effort to teach her those thing.  i want to keep things simple.  i was talking with a white guy when i was doing my masters and i asked him " i have not seen that many white guys going out with any other girl than white, why"  then his answer was similar to mine.  well, we speak same language, we have similar culture and its easier to understand.  believe me, these are important things once you start living together if not while dating.  like few people mentioned, if the guy is mulsim, you really need to think before making any decision.  they are very conservative and and it might be very difficult to cope with new environment.  new environment is not easy.
