Love / Living in Poland with Polish girlfriend: is it possible? [4]

Hi there,

I have a question for you, but before let me tell you the story.

I am Romanian as nationality. I did my Ph.D. in Italy where I met my Polish girlfriend who was doing her Ph.D. as well (4 years since we've got into that relationship). Well, everything beautiful in our lives until we decided to switch from academic to the private sector. I became a freelancer (I earn decently for Romania and Poland), but she got a stable job in Poland. And now our lives started to get complicated. As freelancer, I care less where I live, unless the bureaucracy starts to come into play. On the other hand, I wouldn't like to get married just because of bureaucracy and I and my girlfriend feel about marriage as not being appropriate in this moment (why rush it?).

And here comes my question:
What do I need in order to get temporary residence (more than the 3 months every 6 months - as the law is permitting it now) to live with my girlfriend in Poland? According to the law, there is nothing which could stop me and those like me to apply for it, but nothing to allow me to get such a permit.

Thank you for your help.
