Paul I am very sorry to hear of this. Could it be that she knew how you feel and wanted to try to encourage you into marrying her?
Either way Viv is a nice girl and I would hate to see anything happen to her. Thinking back, I think remember her and you together back from around 2006 or 2007 on or maybe it was even before then.
I hope her stay there is uneventful and that she will eventually return to the Philippines safe.
