Learning German, advice or help appreciated!

And yes, Ihr is confusing because it can mean she, they, and you, with the verb being my best clue as tow which Ihr it is.  I think it's one of those things that we will just learn as we hear it in use more and more.

No, no, no. I never means she. It can only mean her's. For female items as well as persons. And then there's the adress. To give a simple example, think of "your wellbeing". If you aren't close to the person, the polite adress is "Ihr Wohlbefinden". If you are friends or otherwise close to the person, it would be "dein Wohlbefinden". Another hurdle for english natives, since the adress differs between close and removed.

But there's another hurdle that I found hard to take in school. The english "must not". In German, it sounds similar (müssen nicht), but it means something entirely different. In German it means, you're not obliged to, in english, well, it's kind of the opposite.
