Love / Are polish women competative about men? [20]

Recently observed a rather heated row between two polish ladies at a social gathering, one lady accused the other of trying to sleep with her boyfriend (unlikely, he's not pretty!)

Row was sorted and lady plus boyfriend left (him looking very smug) other lady plus her own bloke left shortly after.

This left me as the only female, all the men then chattered on about how fierce polish women are about their men and how they'd all but murder any woman who looked at man they liked!!! They would never blame the man only the woman????? Is there any truth in what the men were saying or was it just a load of vodka fuelled fantasy ???
