Okay, no offence, and I don't want to sound classist or privileged, but a Swiss person is one of the most fortunate, well-off and lucky people. Secondly, Swiss women are kind of Western women, no? Also, being married to someone doesn't mean you're a passport bro. Even when you live in Canada and the United States, there are plenty of immigrants. Marrying then doesn't constitute a passport bro either, lol. It's all about the views and intentions of these bros.
The exchange of choirs is needed and great. Many treat it as a way to care for their partner, which is crucial. I'm conflicted on the idea of "love developing with time", but it's all good as long as it's not an arranged marriage. And I agree we all have different concepts of love.
