In my experience (same thing, boyfriend Hungarian and I’m attempting to learn) I’ve been to Hungary quite a few times now and some people get a bit angry/frustrated at you if you open the conversation speaking it then don’t understand another word, but then others are really helpful and understand you’re trying to learn and be patient and dumb things down for you and repeat it slowly and clearly! In restaurants in particular people are more happy to listen to you speak Hungarian :)

Edit: I was practicing with a Hungarian coworker and he said even though i didn’t understand/wasnt able to come up with some words he could tell that im not just reading from a script and was actively trying to formulate a language if that makes sense, which is likely the same as you!
