This is fascinating, assuming you are both natives of Poland. Is there as much language variance in Poland as in, say, Italy ?

No idea how much variance there is in Italy so not sure how to answer that question.

Italy, the core remnant of the Roman Empire, has unmatched language diversity, often varies even from town to town. It's a colorful mosaic of micro cultures and customs where people from one region using different words for venom/poison is completely normal, in their local dialect. Everyone speaks standard Italian though.

You've never visited Italy ? They're not that far away and I'm sure you'll love it.
