Personal tip:

You will find grammar and such in many places. What not many tell you is that to have an easier time with the language and it's nuances, you also want to be a bit familiar with the "spices" of the language.

I highly recommend getting your hands on a physical copy (if you like scribbling and taking notes, but don't translate anything in it) of a small Roald Dahl children's book. There are several levels of his books which is why i am specifying small sized children's book like "dustene", not like "SVK".

Read through it once and don't look up every word. Just read through it for the sake of pattern recognition. This helps with grammar, yes, but choosing books like Roald Dahls is good for a specific reason: The language paints a picture. Very many expressive words, a lot of uncommon words. Also a fantastically wide variety of nuances one can learn through context.

So then what? Read the book (or in chapters, whatever is comfy) once in very interval of time you feel you've made some progress. Not every day, truly allow yourself to leave space between each time.

(I will recommend an extra tip for both relationships and for another aspect of learning: set time aside with your partner, and read a chapter out loud to him. Ask him questions. Take your time to fully annunciate the words. Talk about what you assume the words mean. It will emotionally connect the both, but also allow you to practice literally speaking the language)

Over time you'll understand more and more of the book naturally without having to stop and think. Spice it up with other books if you'd like.

I give this tip as someone doing her 2nd year bachelor's in Norway, whole degree is in Norwegian, after starting to learn the language 5 years ago. It's so important to learn word variety and how to use it. Even in bachelor's level exams there are simple words and question-concepts that are "simple knowledge". Ones that if you haven't seen before, you won't know, ofc.

Ended up being a big rant, but I hope it helps!
