You were on holiday and you had a lovely girl in your arms doing all the things that make you extremely happy. I know she said she will not have a boyfriend until you come back but do you honestly believe that when in the same breathe she said she will continue to work in the bar? It's the same script for every Tom, Dick and Harry. She makes her money from every drink that was bought for her and even more if she is bar-fined. If she is lucky, she will find someone who will pay for her NOT to be in the business but man, it will cost you. The reality is, she could not afford to be faithful to one man, simple as that.
I'm sure there are other places where you will find someone who could give you the same attention you think only she could give you. Falling in love with a Filipina, getting engaged, married and then filing the visa application is difficult enough without the added problems of a dodgy background.
Godspeed Paul.
