You can survive in English. You want real belonging. Here is how to keep conversations in Dutch when locals switch.

This is the signature challenge at A2-B1. You can survive in English, but you want real belonging. The moment you try Dutch, people switch back "to be helpful".
The fastest way out is daily real input + regular low-pressure speaking where you practice insisting on Dutch.
Create your English trap breaker planUsually to be polite and efficient. Dutch English levels are high, so the moment they detect an accent they often switch. It is rarely meant as rejection, but it blocks your practice.
Answer in Dutch, smile, and use a short line like “Ik oefen graag Nederlands.” Keep going even if they reply in English once. Script a few automatic replies so you do not freeze.
Usually A2–B1: you can survive in English but want real belonging. Below A2 you need more input first; above B1 people switch less often.
Daily real listening (podcasts, Easy Dutch) plus low-pressure speaking with a tutor or exchange partner who agrees not to switch. Frequency beats long rare lessons.
