I recently got beaten up whilst i was with her, in England by 3 Polish guys, i was in hospital for a week, even after they broke my leg they still beat my head on the ground and battered me.
I'm sorry to hear this, but I hope you know it doesn't have anything to do with you being English, or them being Polish. (They could've been of any nationality, and they could've been your own fellows just as easily!) It's just that whenever such cowards see you as an easy victim, or feel confident enough whenever they're outnumbering you, they think it's cool to take out their frustration on you..
I hope that rather sooner than later, these cowards will come across someone they can't handle, which will probably happen. Hey, I wish you a speedy recovery, and whatever you do, don't let it drag you down!
