How do you live 6 years in a country without reaching B1?

You'd be surprised at the lengths some will go to avoid learning a new language.

I've met people who have lived over 20y in a country while working, having and raising kids there and still can't have a half decent basic conversation in the local language.

There is always an excuse: too much work, too little time, too tired or you name it, but the end result is that they are inconveniencing themselves.

Not saying it is OP's case, just some anecdotal obserevations.
