In an attempt to get back in the vicinity of the original topic I would like to suggest that you do not do anything that you would not consider doing in your home country. How many people would buy their girlfriend (or even wife that you lived apart from) a house, etc. Long distance relationships are difficult when you live in the same country and speak the same language, attempting a long distance relationship with someone in Thailand increases the odds against it working. Not impossible, but more difficult to be sure. Use your head, the one on your shoulders, and good luck.
