Just a few questions.....

How many times have you been to Thailand ?
Where did you meet you GF ?
Can you read, write and speak Thai ?
Are you on the same social status ?
Does she have children ?
What are your shared interests ?
What is the age difference ?

I'm not going to disagree with Mirkwood but he is basing his reply on a bargirl or monetary relationship , if that is your case then you're a fucking mug and run a mile if it isn't a case of girl wishing to better herself financially by being involved with you than answer my questions to yourself and go on from there.
