Oh, and language barriers? What language barriers? Love is the international language.

Not once has our marriage ever been seriously in trouble. We know the most important thing, by far, is being faithful to one another. If we are true to each other and have nothing to hide then the rest is easy.

As long as both people are true to each other and do not try to trick each other than the rest is easy. Trust is the most important thing. If both people in a relationship can absolutely trust each other than all other problems are easily overcome as long as there is still love.

I'm not big on giving advice but I would say that if you don't like the culture of the person you are dating then you are likely to have problems with that person sooner or later. It is hard for people to change their fundamental ways. If you are expecting someone to change who they are, then you will probably be disappointed.
