Law / Obtaining Polish citizenship; my boyfriend has dual citizenship (Poland and Canada) [11]

Greetings all,
Hopefully this question wasn't already asked before.

I have become very interested in Poland recently, because my boyfriend is Polish and has expressed a desire to return to his native Kraków. From what he has told me, it seems that it is very hard to emigrate to Poland (besides the the language barrier, I understand that there are certain laws regarding immigration).

Now, I am currently a Canadian citizen, and my boyfriend has dual citizenship (Poland and Canada). I'm assuming that if we married, I could perhaps be entitled to Polish citizenship as well. But, because that possibility is still very far away, what difficulties do you think I would encounter or what steps should I undertake (besides learning the language) in order to obtain Polish citizenship?

Thanks for your help
