Warszawski you might be Gay but I asure you I am not.
Ok, at least that is out in the open
My Polish girlfriend is very jealous and I dont know why . she is the only one I love ..
So why try to find the answer on a forum, this is not a cultural issue, it is personal, if your GF is jealous ask her "why" I am married to a Pole and have never experienced any form of jealousy from my wife, in fact she gives me so much freedom and trust, that I would be a complete fool to spoil the situation we have. So I can assure you jealousy, is not a polish cultural thing, unless you listen to southern of course, then all women are no good inclusive of his mother.
