How do Eastern European cultures and traditions influence online dating?

The main difference between girls from Eastern Europe is that they value attention and a serious approach. Superficial one-night stands are not as popular here as in Western countries. Therefore, it is important to choose the right platform where there are people who are really interested in a relationship. For example, on the Czech marriage agency website https://avodate.com/ you can search for partners by specific criteria: age, country, interests, even family values. This helps you immediately find those who are on the same wavelength as you.

I think many men are simply not ready for this level of traditionalism, especially if they are used to more independent and Western views on relationships.
