We both live in the uk but we're from Poland. Poland's in EU so we can live there but my husband worked legally in UK only for a month.
And he is still in the UK now?
Then yes. I would say call the refuge or women's aid numbers on this page:
http://refuge.org.uk/links-and-useful-numbers/And explain the situation to them.
Do not tell them you are in Poland at this moment however, since they may advise you to stay there.
Tell them you came to the UK with your husband, and detail any abuse (verbal or physical), threats etc, the fact that you are no longer a muslim and he is, and that you have nowhere to go and can't go back to Poland, but don't feel safe with him anymore.
Ask them if they can help, or what they advise.
They are the best people to find out if you could stay with them, and apply for leave to remain in the UK, and have support as you get back on your feet.
