Good advice, in my opinion

I think many men fall 'in love' over the internet, maybe they're falling 'in love' with the idea

same applies to women of a different culture filipino or not, they fall 'in love' with the idea of living in a western country and are therefore blinkered in some respects to the person they're falling 'in love' with.
Tiger's advice of spending time in each others country for a period of time is excellent, then each of you would know if you're in love with the person or the idea. At the end of the day, what's 6 months out of your life when you're planning on spending the rest of it together
