No! Do not underestimate culture differences. Also, many times if a girl from, say, China marries a guy from 'the West', the guy marries 'the whole family with it'. And this is not our custom here. Then the girls ask if her mother, her sister, her father, her brother, can also come over. Been there, seen that, once bitten, twice shy. No!

In my opinion love don t your natioanality ,religion, political views or womething..love skips all these barriers . International love may be somehow interesting but in case when one respectsand get along with the anothers habits , traditions , religion etc.   But in case all these don t exist among couple , sooner or later love grows to hatred and cause many problems...   

To me, either marriage can last longer or not, it depends on the couple keeping the elements of honesty, sacrifice, and mutual respect, support and understanding. Marriage is to live together as a two-in-one (or basic) social institution, sharing the hard and happy times together. So, international love or not, is not the question.   

@sherry, did you run into such problems?

I think an international love perhaps happen...

but If we decided to have an international relationship, we should be carefulll, cause recognize people who far from us is difficult,

and it is not an easy thing to combine two people which have a much differences esspecialy its culture
