Hey Martin , Good question , I think its like U said , different type of challenges and problems , but that doesn't mean it will be more difficult , its Just different form of it. And I think the most important thing is to have the same thoughts and beliefes as U to be able to understand you and your deeds. That's what I think !

it depends on you, on your lover, on your culture, on your family, on her family, on her culture.. each of these are serious parameters that affect the result :) so the case of everyone will result differently :)

it has postiv and negative effects, positiv is: new culture, you learn new things, diffrence in regular days, learning a new language. negative maybe not always: the diffrence in culture can crash if you dont want big diffrences, traditions, languages.

I don't regard marriage as a "challenge"; nor do I see it as a "good idea". If marrying for money and wealth then I suppose you could argue if it is a "good idea" or not. If you marry for love then mixed race marriages are fine. It's only other people's prejudice and ignorance that make them a problem.

In my opinion there are positive (+) and negative (-) aspects ... + Children would grow up with 2 languages +/- big challange and adventure +/- two different culture, education, traditions - one of them have to leave their native country I think, there're a lot more aspects for both sides ...
