Why would a "beautiful woman" send a guy who is thousands of miles away money for a flight to see her and claim that she loves you "very much" after only a month? If she's that attractive why can't she get a man from Poland? It sounds too good to be true.
I watched a program not so long ago about a woman who was duped by a guy she met on a dating site. She went to meet him in his own country and was asked to take a package back with her. She fell for the guise that he was some sort of antiques dealer and in the package was drugs. She ended up getting 25 years in a Cambodian jail.
You're within your rights to choose your own partner but for your own security don't be too trusting. You don't know this woman. She could just be a foil for a drug smuggler to entice you in. You need to consider these things and think with your head not your heart.
