This is RIDICULOUS! I completely agree that this is beyond any claim of jealousy. You're right that its a legitimate safety issue, but it is your W's decision to do this. You can try to talk to her or even ask for assistance from her family or trusted friends. They would have to understand that it is not a wise idea to cross the Atlantic to meet a guy she met on the Internet on a website designed to cater to people who are hurt, emotional, and frequently emotionally susceptible to someone who wishes to take advantage of them.
Did she tell you this? Please don't take this the wrong way, but is there any chance that she is merely playing on your emotions? In the end, she's going to go if she wants to. You need to decide whether this is something you are capable of forgiving. My heart goes out to you and my thoughts and prayers are with you and your family. I'm not sure what this would possibly be, but if there is anything I can do please let me know.
May the road rise up to meet you.
May the wind be always at your back.
May the sun shine warm upon your face;
May the rains fall soft upon your fields and until we meet again,
may God hold you in the palm of His hand.
