I may fall in love with someone of other country.
But when it comes to marry him, i am not sure.
Marriage means obligations. I always feel fear about marriage.
What is more, to marry a guy from other country, there are many things you should consider like where will you live in your country or his country? Will your parents like him. Will there any communication problem between your family and his family. Too many things to consider,when it comes to marriage.Maybe that is why i feel fear about it.
Or just because i haven't met my Mr. right , so everything for me is problem.
Who knows.

as long as we have true feeling with each other, nationality is not a issue,and i am sure we will learn to respect and coalesce both our culture or habits~

I would marry someone with a different nationality but we would both have to respect each others culture, faith and traditions. If there is love, trust and respect in the relationship, it can be successful :)))

Good for you,
But I think Its a good chance to find a right person from another nationality to get married

I would marry someone (haha, not someone anymore <img alt="" src="http://www.italki.com/fckeditor/editor/images/smiley/msn/teeth_smile.gif" /> ) from another nationality. Someone isn't someone in my case anymore. This person is my girlfriend.
