Can't understand the language of Pride and Prejudice

I finally decided to start reading Jane Austen. Started with Pride and Prejudice, I'm only 22 pages in and it feels like I have already read like 80 pages, because I keep re-reading some paragraphs to understand it better 😭

Like I expected the language to be tough to understand. But I didn't realise I would be struggling this much. I'm feeling so dumb ngl. I want to enjoy this book throughout, but pausing and re-reading the difficult sentences doesn't make this a smooth read. Sigh. Anyway, I will still be completing it no matter how long it takes.

Did you all also struggle like me or am I just dumb? Also, any tips to understand it better?
