Life / Help wanted with the Polish law; she got pregnant and returned to Poland [41]

I had a girlfriend from Polen who was getting a deforce, she did get pregnant from me and left back to Poland.
She tells me that as soon the baby will born she will tell me if i may see it or not, we did not fight she did left because here fam told here she will lose all if she stays with me(home in Poland and fam) what can i do to be a real dad for my(our) child ?

Is it possible to fight in court ? because she is still married
