Answering questions about the Dutch language is probably more my cup of tea but since no one replied yet, I decided to give it a try. I looked up "Dutch dating etiquette" on Google and I only found websites explaining what 'going Dutch' on a date is.
To what extent Dutch dating is different from what you are used to, depends on where you are from. Dutch dating etiquette ... With the emancipation of women, I think much of the etiquette has changed (or causes confusion

If it turns out to be a stellar match, you can always come back here to learn the language of your sweetheart.
